send-email: Cleanup { style

As Jakub Narebski pointed out on the list, Perl code usually prefers

sub func {
}

over

sub func
{
}

git-send-email.perl is somewhat inconsistent in its style, with 23
subroutines using the first style and 6 using the second.  Convert the
few odd subroutines so that the code matches normal Perl style.
