Hiya, we took a look in the review club, but I'll try to keep it simple.

There are a bunch of different situations in which one would like to
have an absolute and canonical or a relative path from Git.

I think specifically you are interested in this situation:

I think this would have been useful to see in the cover letter :) There
was a lot of "but why" during the review club meeting.

Looking at the git-lfs issue in question, the problem seems to be "how
to make sure the path Git gives me will match the path Go gives me" -
and like you mentioned in the issue, there are two ways to fix it.

Also, there was some brief wondering: if this option is useful in 'git
rev-parse', would it be useful in other commands too? I thought maybe it
would be more useful as an arg to 'git' itself, but on inspection, not
really - because you wouldn't be able to switch the format in the middle
of a bunch of args, like you can now. The way it's written here,
though, should mean a smooth transition to something like OPT__VERBOSE
or OPT__QUIET if we discover lots of folks would find use.

Thanks for sending it. I'll try and do a detailed review of the patches
themselves. To me, the concept seems sound.
