It updated Bugzilla but it didn't add the PR numbers to the ChangeLog
entries. I still don't (obviously) understand the rules the hook uses
for what to update or the rationale for them. It seems as though
the PR in the subject is used to update only Bugzilla but not also
update the ChangeLogs (why not?)
Because they are two completely separate processes. Verifying the commit
message format is done by a git hook, and you can run exactly the same
checks locally before pushing a commit.
Updating bugzilla is done by a separate and different process, which has
been in place for years (decades?) before we switched to git.
I don't mean to turn this into a contentious back and forth but
"because this is how it works" or "because this is how it's been
done for eons" aren't a rationale, at least not a satisfying one.
Do you not agree that it would be better to be able to mention
the PR or PRs just once and have all our scripts work with it?
If you do then is something keeping us from making those changes?

PS To be clear, I'm suggesting that all these work the same and
update Bugzilla as well as ChangeLogs, both with and without
a space after PR and both with and without a component name after
the PR.
1) PR only in title.
Fix foobar [PR12345]
gcc/ChangeLog:
* foo.c (bar): Fix it.
2) PR (with or without additional text after it) after title and
before ChageLogs.
Fix foobar.
PR12345 - foobar broken
gcc/ChangeLog:
* foo.c (bar): Fix it.
3) PR only in ChangeLogs.
Fix foobar.
gcc/ChangeLog:
PR 12345
* foo.c (bar): Fix it.
The PR component/nnnn part that's
supposed to come before the ChangeLog is used to update ChangeLog
entries but seems to be ignored if it's followed by any text (why?)
See Jakub's reply.
