I think there was agreement between myself and Eric on the last version,
I'm not sure anyone else has expressed an opinion. The problem with
fixing the quoting without any backwards compatibility is that if git is
upgraded while a rebase is stopped read_author_script() will happily use
the broken quoting to create a corrupted author name in the new commit
if the name contains "'".

The compatibility code in the latest version relies on the missing "'"
at the end of the GIT_AUTHOR_DATE line which is fixed by
es/rebase-i-author-script-fix which is now in master. If there is a
release with es/rebase-i-author-script-fix but not
pw/rebase-i-author-script-fix we'll have to rethink as the detection
wont be reliable. I have a branch that fixes read_author_script() to use
sq_dequote() at
https://github.com/phillipwood/git/commits/wip/fix-author-script. At the
moment it has compatibility with broken quoting, but I could strip that
out and then sq_dequote() will return an error with the broken quoting
and the user would have to restart the rebase. So one option is to drop
this series and wait for me to finish the improved solution next month.

Thanks, I'll send some follow up patches to improve the help and
documentation next month.
