As I do not do P4, help in diagnosing why it breaks is appreciated.
If the test script expects a commit, that can be described in two
more more ways, is named one way (e.g. named after a branch) and the
new "favor tags even if they are unannotated" behaviour breaks its
expectation, and the only thing the test _should_ care about is what
commit the result is, then clearly the test script needs to be fixed.
On the other hand, if git-p4 command internally uses name-rev and it
is not prepared to properly handle commits that can be named in more
than one way, the problem would be deeper, as it would mean it can
misbehave even without the change to name-rev when multiple branches
point at the same commit.
