If a layout has NextNoIndent set to true, the following paragraph
is not indented on screen. LyX checks the previous layout for that
style parameter to decide whether to indent or not. Of course,
what matters is the latex output and the on-screen representation
should match this output. Now, when a layout has NextNoIndent==true,
the latex output is correctly not indented, while the on-screen
representation may fail to match this output. This can occur when,
for example, a standard paragraph is nested in the previous layout,
because LyX would check the property of the nested layout instead
of the container layout. Thus, LyX should check the property of a
previous layout at the same depth for correctly deciding whether
a paragraph has to be indented or not.
See also http://www.lyx.org/trac/ticket/9055#comment:12 for an
example document where the previous scenario actually occurs.
Do not forget last word of paragraph in completion
With the old code, the last word of a paragraph would not be added in
the completion list. The key difference is to pass `from' instead of `pos'
to FontList::fontiterator.
Make use of otexstream also in external::writeExternal
This was not necessary when LyX was generously outputting newlines.
As it may happen that the output produced by writeExternal (the
result of an external inset) starts right at the beginning of a
line, if otexstream does not know that something is already on
the line, the iomanip-like variable 'breakln' fails to actually
break the line.
This is what LyX was previously doing. It has no effect on vertical
spacing but, for example, sectioning commands stand out on the output.
The parbreak is not output if an environment follows or the alignment
of the current or next paragraph is changed.
Also remove some superfluous code.

Fix bugs #8546 and #9055, and introduce new separator inset.
The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.

Fix bug #9112: There is a test here that seems intended to catch the
case where there are unbalanced braces, but it comes too late. In that
case, we try to check cmd[docstring::npos] and crash.
This has the advantage of simplifying our code and to produce the
correct output: the small capitals should have the exact same width as
the lower case letters.
The slanted fonts are also translated to oblique on Qt side, but this
does not seems to have an effect in my testing. It may be that proper
oblique fonts need to be installed.

Fix lyx2lyx math package defaults (bug #9069)
lyx2lyx sets all new math packages to off when converting from old formats.
This is correct if any command which would cause an automatic package loading
exists in the document. However, it is wrong if no command exists: This leads
to problems if later a command is added (bug #9069), which is especially
annoying for templates.
The fix consists of two parts:
1) convert_use_package() considers now the used commands like
revert_use_package(), and uses them to decide whether to set the package to
auto or off.
2) convert_undertilde() and revert_undertilde() use a slightly adjusted copy of
convert_use_package() and revert_use_package(), so that the bug is also
fixed for undertilde. We cannot use the latter functions directly, because
of "\usepackage undertilde" vs. "\use_undertilde".

When doing the lyx2lyx round trip of the 2.0.8 user guide from format
413 -> 474 -> 413 you do not get a zero diff. The most important problem is
caused by the conversion of the argument insets to the old syntax: This
conversion adds an additional empty line (harmless), and it destroys the
document structure if the first inset in e.g. a subsection is not an argument
inset, but e.g. an index or label inset.
The fix is quite easy: Ensure that the paragraph begin is set to the first
argument inset.

Fix warning in lyx2lyx 2.0<->2.1 round trip
revert_justification() issues a warning if the \justification parameter does
not exist, and LyX itself always writes it unconditionally as well, so add it
also in lyx2lyx when converting old documents.
Currently this does not have any user visible effect, but it decouples the
default value of BufferParams::justification from the conversion of old
documents: Now it is possible to set the default to false in LyX, and old
documents will still be converted correctly.

Make iparserdocstream more like std::istream
In C++98 std::istream does not use an operator bool(), but an operator
void*() instead, which prevents some unwanted conversions (this is one
possible implementation of the safe bool idiom).
In C++11 std::istream uses explicit operator bool, which prevents the unwanted
conversions using a new language feature.
This change does not have any effect on correct code, but prevents some
mistakes.
cmake: Objective-C compilation support with clang and C++11
This fixes an issue when compiling with C++11 flags on: the
objective-C clang compiler produces an error. This patch set
the -std option to ansi for the Objective-C sources.
This option is going to be mandatory starting with automake 2.0.
LyX is able to use this since version 2.1, but it turns out that it is
badly implemented in versions of automake older than 1.14.
We rely on some (undocumented) symbol to detect automake 1.14 and
use the subdirs-objects option in this case.
