[PATCH v3] Make git send-email accept $EDITOR with arguments

[Gustaf Hendeby <hendeby@isy.liu.se>]

Currently git send-email does not accept $EDITOR with arguments, eg,
emacs -nw, when starting an editor to produce a cover letter.  This
patch changes this by letting the shell handle the option parsing.

This is based on Junio's suggestion on most readable and compatible
solution.  I'm not sure if it is identical to the C solution for git
tag, but it seems to be a reasonable solution.
