[PATCH] 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 fixes
this in the simplest way possible, assume all spaces separates either
the command from the first argument, or two arguments.  This should
work in most cases, but will break with quoted strings embedded spaces.
An example of a problematic case is when there is a space in the path
to the command.

This is related to the problems recently observed in the built in git
commit and git tag.  I guess the behavior of git send-email has been
the same from the start, but having it treat $EDITOR substantially
different from that of git commit and git tag seems like bug or at
least something that should be avoided.

I'm not completely satisfied with the problem with embedded spaces,
but my Perl skills aren't good enough to do anything about it.  If
anyone have any suggestions on how to do it, it would be greatly
appreciated.  None-the-less, even with this shortcoming, I think this
is a step in the right direction.
