The patch is twofold: it moves the option consistency checks just under
the parse_options call so that it doesn't get in the way of the tree
reference vs. pathspecs desambiguation.
The other part rewrites the way to understand arguments so that when
git-checkout fails it does with an understandable message. Compared to the
previous behavior we now have:
- a better error message when doing:
git checkout <blob reference> --
now complains about the reference not pointing to a tree, instead of
things like:
error: pathspec <blob reference> did not match any file(s) known to git.
error: pathspec '--' did not match any file(s) known to git.
- a better error message when doing:
git checkout <path> --
It now complains about <path> not being a reference instead of the
completely obscure:
error: pathspec '--' did not match any file(s) known to git.
- an error when -- wasn't used, and the first argument is ambiguous
(i.e. can be interpreted as both ref and as path).
