From: Cornelius Weig <cornelius.weig@xxxxxxxxxxx>
Git-checkout completes words starting with '--' as options and other
words as refs. Even after specifying a ref, further words not starting
with '--' are completed as refs, which is invalid for git-checkout.
This commit ensures that after specifying a ref, further non-option
words are completed as paths. Four cases are considered:
- If the word contains a ':', do not treat it as reference and use
regular revlist completion.
- If no ref is found on the command line, complete non-options as refs
as before.
- If the ref is HEAD or @, complete only with modified files because
checking out unmodified files is a noop.
This case also applies if no ref is given, but '--' is present.
- If a ref other than HEAD or @ is found, offer only valid paths from
that revision.
Note that one corner-case is not covered by the current implementation:
if a refname contains a ':' and is followed by '--' the completion would
not recognize the valid refname.
