I have modified the parser to not drop any spaces anymore. The result is
that the Userguide roundtrip works better. Apart from the preamble, a
diff -u Userguide.tex Userguide-new.tex
shows now almost only real problems. Another benefit is that it is possible
to add support for verbatim and similar environments. A few bugfixes and
enhancements are added, too. The drawback is that we have more calls of
Parser::skip_spaces() now, but some of them will go with the implementation
of Jean-Marcs suggestion to handle \command and
\begin{command}...\end{command} by the same code. Also some comments are
still dropped, but we issue a warning now.
See the Changelog and comments in the source for more details.
For whose who want to test: The attached Userguide.diff removes some
occurences of bug # 1428 from the Userguide.
Comments?
