    bitbake: fetch2/git.py: References must match exactly
    
    Previously the code used to match a reference to its SHA-1 in
    _latest_revision() used the Python "in" operator, which made it match
    if the reference matched the beginning of an existing tag or
    branch. This test, however, must be exact. I.e., either the reference
    matches a tag or branch exactly, or it does not match at all.
