tclint, pre-commit and patch submissions

Hi,

I've recently added a tclint pre-commit hook, and started cleaning the 
testsuite.

The current status is that all gdb.* dirs are done, with the exception 
of gdb.stabs (which is going to be removed, so I skipped it).

My question is what to do with patches adding new test-cases or 
modifying existing test-cases.

If these patches are not tclint-clean, then after commit this command:
...
$ pre-commit run tclint --all-files
...
will start showing new tclint errors.

One thing that could be done at that point is to ask the 
submitter/committer to fix the tclint errors.

But there's no formal agreement atm that this need to be fixed.  I've 
proposed the hook, and Tom Tromey approved it, but that's just two 
maintainers.

So I'd like to know the opinion of other maintainers.

Possible outcomes of this discussion could be that:
- we get rid of tclint in pre-commit and forget about it
- we drop one or more error categories in gdb/tclint.toml
- we require submitters to run pre-commit before submission
- we make the repo refuse commits that are not pre-commit clean
- nothing changes, and submitters can use all/some/no pre-commit hooks
   for their own submissions

Thanks,
- Tom
