Is this for another PR? I don’t see the change here.

It's in this PR, it's in the change to tests/test_specifiers.py

I tried to merge branch with 'main' to make sure this PR was still good, but forgot I don't have automatic CI rights, if someone could approve CI run I'd be appreciative.

Anything blocking this? Do I need to do anything for a changelog entry here?

#788 (comment) has some examples. We probably should have some tests for those.

Added specifier tests to match.

The specifics of this came up today in astral-sh/uv#6640

It reminded me to check this PR, it seems there was a transient CI error, I added some more tests (and after correcting them) the transient CI error vanished.

I'm going to give @pradyunsg a chance to (dis)agree to the semantic change before I merge.

Thanks, @notatallshaw !
