I think "should" is a bit too strong a word.  While yours is a bit
more explicit on _what_ the solution is, "hook: test -a|o is not
POSIX" already implies that we are fixing that non-posix-ness by
rewriting, and it is obvious (cf. Documentation/CodingGuidelines)
what the right rewrite should be.

One thing the original does a bit better tha yours is that it tell
us _where_ the problem is.  So, perhaps

    sample hook: use "test ... &&/|| test ..." instead of "test -a/-o"

But I find the original just fine.
