   9Prepare each commit with its patch since our-head forked from upstream,
  10one file per patch, for e-mail submission.  Each output file is
  11numbered sequentially from 1, and uses the first line of the commit
  12message (massaged for pathname safety) as the filename.
  13
  14When -o is specified, output files are created in that directory; otherwise in
  15the current working directory.
  16
  17When -n is specified, instead of "[PATCH] Subject", the first line is formatted
  18as "[PATCH N/M] Subject", unless you have only one patch.
