Ship sample hooks with .sample suffix
We used to mark hooks we ship as samples by making them unexecutable, but some filesystems cannot tell what is executable and what is not. This makes it much more explicit. The hooks are suffixed with .sample (but now are made executable), so enabling it is still one step operation (instead of "chmod +x $hook", you would do "mv $hook.sample $hook") but now they won't get accidentally enabled on systems without executable bit.

+# To enable this hook, rename this file to "pre-commit".
+
+# This is slightly modified from Andrew Morton's Perfect Patch.
+# Lines you introduce should not have trailing whitespace.
+# Also check for an indentation that has SP before a TAB.
