This assumes that remote X always has its tracking branches in
refs/remotes/X/*. But that is really dependent on how the fetch refspec
is set up. True, it will be like that for remotes set up by "git remote"
or "git clone", but it isn't universal (and we have tried not to make
that assumption elsewhere, like when finding upstream branches to merge
from). Doing it right would mean interpreting the refspecs in
remote.*.fetch.
But this is not necessarily about actual remotes, I don't think. It is
really about the names of refs we have, and that you could reference,
but that are not actual tracking branches. It's just that refs/remotes
is the obvious hierarchy there.
But I wonder if what you should do instead is to iterate through each
ref, removing refs/heads/* and refs/tags/* (which are uninteresting, as
they are already part of the normal ref lookup), and then suffix-match.
So looking for "next" would find "refs/remotes/origin/next", or even
"refs/foobar/next" if you had some "foobar" hierarchy.
It would also match "foo" to "refs/remotes/origin/jk/foo". I'm not sure
if that is a feature or a bug, though.
Aside from that, I can't think of anything wrong with the idea.
Personally I find it more chatty than I would want, because I know what
I'm doing. So I would suggest adding an advice.suggestBranchName config
option to voluntarily suppress it.
