I actually read the result of applying the patch before sending the

I know. What it boils down to I think is this.
If somebody said:
The path to the hooks directory can be specified relative, and
it is relative to something described elsewhere.
Hooks are run either at the root of the working tree or in
GIT_DIR, and they are not affected where the user's current
directory is (they cannot even know where it is).
you interpret, with the knowledge that "we first determine in which
directory to run a hook with a given name, go there, and then look
for the named hook", the directory hooks are run in is NATURALLY the
directory relative paths the hooks are found are relative to.
My problem was that it is only natural if you have that knowledge.
A reader who starts with a mindset "Git first finds the hook to run,
and then goes to the directory to run it in", it is not naturally
clear. The latter is specified by two rules, one for a bare and the
other for a non-bare repository, and it is very clear. The former
is specified nowhere, unless you give a hint to fix the mindset of
such a reader.
