--stdout was not mentionned, and the description for the case where -o was not given was thus incomplete. Signed-off-by: Yann Dirson <ydirson@altern.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

USAGE='[-n | -k] [-o <dir> | --stdout] [--signoff] [--check] [--mbox] [--diff-options] <upstream> [<our-head>]'
|
|
LONG_USAGE='Prepare each commit with its patch since our-head forked from upstream,
|
|
one file per patch, for e-mail submission. Each output file is
|
|
numbered sequentially from 1, and uses the first line of the commit
|
|
message (massaged for pathname safety) as the filename.
|
|
|
|
There are three output modes. By default, output files are created in
|
|
the current working directory; when -o is specified, they are created
|
|
in that directory instead; when --stdout is specified, they are spit
|
|
on standard output, and can be piped to git-am.
|
|
|
|
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 --mbox is specified, the output is formatted to resemble
|
|
UNIX mailbox format, and can be concatenated together for processing
|
|
with applymbox.'
