Using
coo
to open a branch under the cursor that started with 4+ hexdigits (e.g., 1111-feat) would fail with the error
fatal: invalid reference: 1111.
This happened because the prior regex would consider these branch names
as commits when determining whether to treat what was under the cursor
as a branch or commit.
This changes the regex to use a negative look-ahead to further tighten
the match for a commit and require that a match on 4+ hex digits also
not end with a non-hex digit.
Resolves #2085.
