send-email: use catfile() to concatenate files
Change send-email to use Perl's catfile() function instead of "$dir/$file". If send-email is given a $dir that ends with a / we'll end up printing a double slashed path like "dir//mtfnpy.patch". This doesn't cause any problems since Perl's IO layer will handle it, but it looks ugly. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
