-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.
+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 -o is specified, output files are created in that directory; otherwise in
-the current working directory.
+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 -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.
