[PATCH] Fix over-simplified documentation for 'git log -z'

[PATCH] Fix over-simplified documentation for 'git log -z'

[Björn Gustavsson]

In commit 64485b4a, the documentation for 'git log -z' was
simplified too much. The -z option actually changes the behavior
of 'git log' in two ways: commits will be ended with a NUL
instead of a LF (correctly documented) and the --raw and
--numstat will have NUL as field terminators (omitted in
the documentation for 'git log').

I wrongly assumed that 'git log' ignores the --raw
and --numstat options, because I tested it in a repository
with only merge commits. They do have an effect for
plain commits, and consequently -z will modify their
behavior for 'git log' too.

This patch applies on 'next'.

 Without this option, each pathname output will have TAB, LF, double quotes,
 and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
 respectively, and the pathname will be enclosed in double quotes if
 any of those replacements occurred.
