bug#28758: texlive@2017: Update to at least revision 44704 to address bug in latexdiff

[Adonay Felipe Nogueira]

Since Perl 5.26.0, braces in RegExps have to be escaped if one wants
Perl to match these literally.

However, texlive@2017 --- from June 4th, 2017 --- doesn't implement the
fix made to latexdiff ([1][2]) --- made into TeX Live repository in June
26th, 2017.

Without the fix, `latexdiff' command is unable to work (its goal is to
generate "TeX-command-and-group-aware" differences between LaTeX
documents).

There hasn’t been a new release tag that includes this change, and I’m
not comfortable with just increasing the revision to an arbitrary
development revision.

Is this something we can apply as a patch to a single package?  If so,
which package requires this fix?

I have downloaded TeX Live repository but unfortunatelly I found out
that the directory structure of the repository is different than the
release's.

An option would be to make latexdiff into a separate package, with
a name such as "texlive-texmf-scripts-latexdiff", and take the source
from either latexdiff CTAN page ([1]) or their development repository
([2]) and in either case remove the latexdiff from the "texlive-texmf"
package. But in this option, I don't know if latexdiff would need other
parts of TeX Live to be updated in order to work correctly.

I'm closing this >3 years old bug as it was reported against Tex Live
2017, and Guix is now using 2019, which surely includes the above fix.

Closing.

Thanks for the report,

Maxim
