format-patch: Add configuration and off switch for --numbered

Benabik · gitster · commit 49604a4d62d9 · 2007-11-04T01:26:30.000-08:00
format.numbered is a tri-state variable.  Boolean values enable or
disable numbering by default and "auto" enables number when outputting
more than one patch.

--no-numbered (short: -N) will disable numbering.
