perlhack: We use p.r's, not issue tracker; clarify commit msgs

[khwilliamson]

This adds extensive discussion about what to put in a commit message, and especially the title.

• This set of changes does not require a perldelta entry.

I do not approve of this pull request.

My initial reaction is: It doesn't practice what it preaches. Its subject line largely consists of "We use p.r's, not issue tracker" -- but the pull request itself only mentions 'issue tracker' in the deletion of two lines from the existing documentation.

More generally, what constitutes a good commit message is something that is always going to be up for argument. The content of this pull request would make a great post on a blog, but it's not something I think we need to codify in our official documentation at this time.

Quoth @jkeenan

That sounds like a very good reason to document the standards.

And more missing "commit"

[guest20]

Couple of quick ones:

• Should these PRs explicitly target bleed⸸?
• What's the difference between perlhack, perlgit, and perlpolicy again?
• Why is the "Super quick start guide" eleven steps and nearly 2 pages?
  __
  ⸸. and isn't it insensitive to haemophiliacs to call the branch bleed?

[khwilliamson]

guest20, It isn't bleed, it is blead. I don't know the differences between these various pods. That is above my pay grade, and thus the scope of this PR. And everything eventually targets blead. I guess it isn't super quick any more; but again that is outside the scope of this change

[khwilliamson]

kid51, Obviously I think this is worth doing, or I wouldn't have proposed it. There will be commit messages that don't follow this. But it sets a goal to work towards, and text to give to new people on the project so it doesn't have to be repeated over and over. And this merely expands on what was already there, and in the same spirit.

I think I've used git add -i once ever. /me hugs git gui and emacs magit.
