[PATCH 3/3] git send-email: turn --compose on when more than one patch.

[Pierre Habouzit <madcoder@debian.org>]

Automatically turn --compose on when there is more than one patch, and
that the output is a tty.

Do not print the list of files sent anymore in that case, as the list is
shown in the summary editor.
