Subject: format-patch: add --reroll-count=$N option
X-Git-Tag: v2.4.6~5^2~2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/5fe10fe80a04a57affbaa35258f498bc1acb05e9?hp=5fe10fe80a04a57affbaa35258f498bc1acb05e9

format-patch: add --reroll-count=$N option

The --reroll-count=$N option, when given a positive integer:

- Adds " v$N" to the subject prefix specified.  As the default
subject prefix string is "PATCH", --reroll-count=2 makes it
"PATCH v2".

- Prefixes "v$N-" to the names used for output files.  The cover
letter, whose name is usually 0000-cover-letter.patch, becomes
v2-0000-cover-letter.patch when given --reroll-count=2.

This allows users to use the same --output-directory for multiple
iterations of the same series, without letting the output for a
newer round overwrite output files from the earlier rounds.  The
user can incorporate materials from earlier rounds to update the
newly minted iteration, and use "send-email v2-*.patch" to send out
the patches belonging to the second iteration easily.
