Subject: [PATCH 1/5] Git.pm: add unquote_path()
But I think it is more customary to remove the implementation in the other file and adjust the existing callers to call this new one in this same commit. And then in follow-up commits, improve the implementation in Git.pm.
When that happens, the subject would become
Subject: [PATCH 1/?] add-i: move unquote_path() to Git.pm
and the first sentence in the body would be tweaked ("move unquote_path() from ... to Git.pm so that ...").

Good to notice and document the lack of '\a' which does get used by quote.c::sq_lookup[] when showing chr(7).

In an early part of "sub unquote_path" we see dq spelled as "\042" and in the original cquote_map, this is also defined with "\042". I do not think you want to change the above to make them inconsistent.

Squash in a change to remove the original from add-i and adjust the caller to call this one (you may not have to do anything as it uses Git.pm already, or perhaps "use Git qw(unquote_path)" or something?) and it would be perfect ;-)
Thanks.
