[PATCH v4 0/1] ref-filter: add new "signature" atom

This patch is not different from previous version(3), this is because the previous version(3) could not show the difference from version(2) of the patch. I will explain every change from the first version <https://public-inbox.org/git/pull.1452.git.1672102523902.gitgitgadget@gmail.com/> to version 3 <https://public-inbox.org/git/20230110005251.10539-1-nsengiyumvawilberforce@gmail.com/> because I first had a big trouble in transitioning from gitgitgadget to using git send-mail

***THE FOLLOWING ARE THE CHANGES*** a) From the first version to version 2 <https://public-inbox.org/git/pull.1428.git.git.1673254961028.gitgitgadget@gmail.com/> Version 2 addresses all Junio's comments for version 1, the comments are here. <https://public-inbox.org/git/xmqqo7rpvb83.fsf@gitster.g/> ->summary of the changes i) I changed the commit message to detail more about the feature I am introducing. ii) Introduced a new helper function in ref-filter.c called parse_signature_option() and handled !arg case first. iii) Used the above helper function to eliminate the repetition that was in grab_signature() for checking different signature option. iv) I also moved check_commit_signature(commit, &sigc) out of the to avoid running GPG twice.still this change is in grab_signature() in ref-filter.c. v) add a new test in t6300 to test bare signature atom(%(signature)) since I had missed it

NB: I did not change the parser function name as he suggested, I
think my commit message was misleading.

b) from version 2 to version 3 <https://public-inbox.org/git/20230110005251.10539-2-nsengiyumvawilberforce@gmail.com/>

->summary of changes i) Got rid of test for bare signature atom. This is because the test was passing for some CI tests(different machines) and some others were failing.

Best Regards, Wilberforce
