[PATCH 1/2] git-send-email.perl: support no- prefix with older GetOptions

[Junio C Hamano <gitster@pobox.com>]

From: "Kyle J. McKay" <mackyle@gmail.com>

Only Perl version 5.8.0 or later is required, but that comes with
an older Getopt::Long (2.32) that does not support the 'no-'
prefix.  Support for that was added in Getopt::Long version 2.33.

Since the help only mentions the 'no-' prefix and not the 'no'
prefix, add explicit support for the 'no-' prefix when running
with older GetOptions versions.
