755 * 1. A space must be suppressed. Example: The lyxcode case below
756 * 2. A space may be suppressed. Example: Spaces before "\par"
757 * 3. A space must not be suppressed. Example: A space between two words
759 * We currently handle only 1. and 3 and from 2. only the case of
760 * spaces before newlines as a side effect.
762 * 2. could be used to suppress as many spaces as possible. This has two effects:
763 * - Reimporting LyX generated LaTeX files changes almost no whitespace
764 * - Superflous whitespace from non LyX generated LaTeX files is removed.
765 * The drawback is that the logic inside the function becomes
766 * complicated, and that is the reason why it is not implemented.
