[PATCH] - git-send-email.perl

[Joe Perches <joe@perches.com>]

Here's a path to enable a command line option
that takes a string argument

	cc-cmd

This modifies the @cc array to include whatever
output is produced by cc_cmd $patchfile

cccmd can be stored in a config settings file

previous versions of this patch were submitted
against an older version of git-send-email.perl
