+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.
When --mbox is specified, the output is formatted to resemble
UNIX mailbox format, and can be concatenated together for processing
