[PATCH v4 0/4] githooks.txt improvements + core.hooksDirectory

In this version of the series I've hopefully addressed all the comments that came up on the list after the last one, and a few fixes I noticed myself, e.g. a couple of grammar errors and a broken asciidoc syntax.

I've combined both the githooks.txt documentation improvements and the core.hooksDirectory patch into one series. Although they're logically different things I think it makes more sense to combine them for ease of reading, since the core.hooksDirectory documentation refers to some documentation I fixed earlier in the series.

Ævar Arnfjörð Bjarmason (4):
  githooks.txt: Improve the intro section
  githooks.txt: Amend dangerous advice about 'update' hook ACL
  githooks.txt: Minor improvements to the grammar & phrasing
  hooks: Add ability to specify where the hook directory is
