Some of the permission has already been granted. There is a file in
libgit2 documenting who has done so. The set difference is:
$ git log --format=%an parse-options.[ch] | sort -u >need
$ perl -lne 'print $1 if /^ok\s+(.*) </' libgit2/git.git-authors >have
$ comm -23 need have >remaining; cat remaining

which gets us halfway there. A few of the remaining contributions are
quite small, too:
$ git blame --line-porcelain parse-options.c |
perl -lne 'print $1 if /author (.*)/' |
sort | uniq -c |
perl -pe 's/(\d+) /$1\t/' >count
$ join -1 1 -2 2 -t "`printf '\t'`" -o "2.1 2.2" remaining count

Fixing a typo or tweaking the "static" designator on a function is
probably not copyrightable. And some of the medium-sized bits could
possibly be dropped. Still, it is nice to be mindful of the
contributions of others and get permission from everyone.
At any rate, the parse-options code would be linked into the new git2
binary, which should probably be GPL'd, anyway.
