Remove the mathed "BUGS" file (#3493)

Jürgen cleaned up the previous contents of this "BUGS" file. What
was left (before the rm in this commit) had been written in 2001 at
2dd1a460, and it is not clear if it is still relevant.

-   Flattening macros. Sometimes it's annoying the fact that once you have
- written a macro, you can't touch at it's "constant parts". I call flattening
- to the process of substituting all macros with LaTeX code.
-
-   Task: designing a macro substitution system that reads from a file
- (possibly the same file as the document's) the macros and parses the document
- doing the appropriate replacements
-
-  This is very useful, because sometimes you have a big expression in a macro
- and you want to change an index only. What do you do then?. You retype
- everything (perhaps several times in the document) or you create extremely
- generic and parametrizable macros that aren't very fast to fill in the
- majority of cases.
