[PATCH] Documentation/process: use scripts/get_maintainer.pl on patches

[Krzysztof Kozlowski]

Explain that, when collecting list of people to Cc the patch,
scripts/get_maintainer.pl should be used on patches, not on the
directories.  The behavior is quite different, because with "-f" on
a directory, the maintainers of individual files will not be shown.

It seems using the script on patches is not obvious and it already
caused some misunderstandings.

 If all else fails, talking to Andrew Morton can be an effective way to
 track down a maintainer for a specific piece of code.
