While git-request-pull(1) is written as a shell script, for it to function we depend on Perl being available. The script gets installed unconditionally though, regardless of whether or not Perl is even available on the system. When it's not available, the `@PERL_PATH@` variable may be substituted with a nonexistent executable path and thus cause the script to fail. Refactor the script so that it does not depend on Perl at all anymore. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
