In theory, yes. I was definitely over-simplifying things above.
You seem to be interested in the longer version of my reasoning so
I'll write it up:

- I believe that the only thing that prevent ikiwiki.cgi from
allowing anyone with an Internet connection to edit arbitrary files
under wiki/src/ is our lockedit plugin configuration.
There's already been security issues in this part of the ikiwiki
code so I'd rather not rely on it when we can cheaply avoid it.

- For various reasons we tend to review changes under wiki/src/ less
carefully than other changes so if someone exploited an ikiwiki bug
and modified that pre-commit hook, chances are their code would run
on a number of our systems before someone notices the problem.

So yeah, in theory, assuming no software bugs, it's safe to put such
code under wiki/src/; but it increases attack surface a fair bit, with
no substantial benefit I can think of, so let's err on the safe side,
as you did already, thanks!

Now, this hook runs wiki/src/contribute/l10n_tricks/check_po.sh so the
problem I'm describing above is still there. This could not fixed in
pre-commit hook by calling submodules/jenkins-tools/slaves/check_po
directly instead of going through the symlink.
