+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 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.
