OK.  An obvious alternative may be to see if the expected hooks path
is a directory and use the contents.  If ".git/hooks/pre-commit" is
a single file, we know it is the single hook as before, and if it is
a directory, we know that is not a custom made (i.e. from the world
before this series supported in the core-git) multi-hook setup.

This part may become the most controversial in the whole topic, but
a design discussion is helped by having a concrete proposal that
makes its own design decision, and this is the simplest design of
the failure case that is the easiest to understand.

Thanks.  Let's see how the review discussion goes ;-)
