[Bug-AUCTeX] Re: 11.85; TeX-format-filter incorrectly unbreaks lines

[Ralf Angeli]

Please keep the mailing list copied.  Also, I've reformatted your post
(except for the part with the LaTeX output) since the lines were longer
than 80 characters.

Is this copied from the output buffer in AUCTeX or from a terminal or
log file?  If it's from AUCTeX, perhaps the linebreaks at column 79 have
not been removed correctly?

The funny thing is that there is a regexp in `TeX-parse-error' which
tries to deal with output containing linebreaks:

(re-search-forward "\r?\n\
\\(?:.\\{79\\}\r?\n\
\\)*.*\r?$")

But this should work equally well with the situation where _all_
linebreaks were removed.
