Patch RFA: Support non-ASCII file names in git-changelog

[Ian Lance Taylor via Gcc-patches]

As discussed at
https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561995.html ,
the ChangeLog checker does not correctly handle files with non-ASCII
file names.

This patch fixes the problem.  I have little experience with Python,
so I may have made some foolish mistakes here.

OK to commit?

Thanks.

Ian

* gcc-changelog/git_repository.py: Ignore quotation marks added by git
for non-ASCII file names.
