Ah, I had not understood that. To ensure clarity, here are the two options:

1. `opam pin -k git add $PKG $PATH` -> $PKG#$BRANCH
2. `opam pin -k git add $PKG $PATH` -> $PKG which tracks the currently
checked out branch

I believe you propose 1 which removes branch-less pins altogether and
does not refer to local state. I like this design. Re-pinning can be
used to switch branches.
