send-email: relay '-v N' to format-patch

Browse Source 
send-email relays unrecognized arguments to its format-patch call.
Passing '-v N' leads to an error because -v is consumed as
send-email's --validate.  For example,

  git send-email -v 3 @{u}

fails with

  fatal: ambiguous argument '3': unknown revision or path not in the
  working tree.  [...]

To prevent this, add the short --reroll-count option to send-email's
main option list and explicitly provide it to the format-patch call.

There other format-patch options that send-email doesn't relay
properly, including at least -n, -N, and the diff option -D.  Punt on
these because dealing with them is more complicated:

 * they would require configuring send-email to not ignore option case

 * send-email makes three GetOptions() calls with different sets of
   options, the last being the main set of options.  Unlike -v, which
   is consumed by the last GetOptions call, the -n, -N, and -D options
   are consumed as abbreviations by the earlier calls.
