Yeah, modulo those styles issues your v3 and v4 addressed, and use of
strbuf.
It might feel that we went full circles, wasting your time. But it's not.
We found out that the final series would look like this:
[1/3] Introduce expand_user_path();
[2/3] Using #1, introduce git_config_pathname() and use it to parse your
two variables;
[3/3] Update the sole caller of user_path() to use expand_user_path().
Patch #1 and #2 can be squashed into one if you want. Also you do not
have to do #3 yourself if you do not feel like it (but now we know how the
code would look like, why not?).
Thanks to these three initial rounds, we know whoever implements #1 knows
what kind of interface the (to-be-rewritten) user of user_path() would
want, so #3 will become much cleaner. We made progress.
Thanks.
