Subject: format-patch let -k override a config-specified format.numbered
X-Git-Tag: v1.6.3.2~14^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ca6b91d29b7ea937b71f62bf00ba7750f3e594ce;p=git.git

format-patch let -k override a config-specified format.numbered

Let a command-line --keep-subject (-k) override a config-specified
format.numbered (--numbered (-n)), rather than provoking the
"-n and -k are mutually exclusive" failure.
* t4021-format-patch-numbered.sh: Test for the above
