Mike McCormack 19bb732728 Allow format-patch to attach patches
The --attach patch to git-format-patch to attach patches instead of
inlining them.  Some mailers linewrap inlined patches (eg. Mozilla).

USAGE='[-n | -k] [-o <dir> | --stdout] [--signoff] [--check] [--diff-options] [--attach] <his> [<mine>]'
LONG_USAGE='Prepare each commit with its patch since <mine> head forked from
<his> head, one file per patch formatted to resemble UNIX mailbox
format, for e-mail submission or use with git-am.
Each output file is numbered sequentially from 1, and uses the
first line of the commit message (massaged for pathname safety)
as the filename.
When -o is specified, output files are created in <dir>; otherwise
they are created in the current working directory. This option
is ignored if --stdout is specified.
When -n is specified, instead of "[PATCH] Subject", the first
line is formatted as "[PATCH N/M] Subject", unless you have only
one patch.
When --attach is specified, patches are attached, not inlined.'
