[PATCH v4 0/3] '@' as a synonym for 'HEAD' in patch mode

Since v3, I have taken Junio's suggestion to replace '@' with 'HEAD' at the beginning of run_add_p(). Due to this, I no longer think we need to have/export the_user_meant_head() function just for the single instance in builtin/checkout.c. Therefore, I have hardcoded the '@' condition in builtin/checkout.c.

Also, Phillip mentioned that the PERL prerequisites in the test files that are touched by this series are unnecessary and therefore I have attached a patch to remove them.

  add-patch: remove unnecessary NEEDSWORK comment
  add-patch: classify '@' as a synonym for 'HEAD'
  add -p tests: remove Perl prerequisite
