I'm not sure if editing the title just makes a bunch of noise and is actually unhelpful, but if it's good, you could probably improve it by clarifying the pr title to mention the subsystem e.g. "manpages: fix 5 self-references".

Edit: to reviewers: is it correct and acceptable for me, as someone who is not any type of authority in this project, but is interested and has contributed/familiarized themselves with this subsystem, to leave approval after I read it and think it's very nice?

thank you @concussious for the review and the tidbits.

The amount of detail to put in a git commit has been a learning, i went with being more extensive as this is pretty new. Your suggestion on maybe less is more is a good thing and will try that with the next one (if that makes sense to do).

denoting this commit message is aligned to the conventions for the project.

hi @mhorne if it would not be too much trouble, could you take a look at this pull request?

I went through and aligned things, got it down to 1 commit and did the commit log magic on it.

Thank you in advance.
