[PATCH 1/4] apply: Clarify the description of -z

["Björn Gustavsson" <bgustavsson@gmail.com>]

The description of -z says that a machine-readable format will be
used "when showing the index information". From that description,
it is not at all clear which other option it will modify the
behaviour of. Explicitly state that -z modifies the behavior
of --numstat.

Also correct the description of the "munging" that takes places
in the absence of -z, namely that apart from the characters
mentioned, double quotes are also escaped and that the pathname
will be enclosed in double quotes if any characters are escaped.
