bug#21183: 11.88; Wrap line break references to labels

[Ortner, Christoph]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug
tracker.  Visit http://debbugs.gnu.org/cgi/pkgreport.cgi?pkg=auctex
to browse existing AUCTeX bugs.

If I do automatic line wrap in paragraphs with latex labels, e.g.,
\ref{eq:a long descriptive label}
then it will often be separated into two lines, and the reference
breaks. Same problem with labels themselves in fact.
