Git workflow

[xaur]

Initially it was: commit as it goes and squash some.

Currently it is: minimize master commits count but keep individual contributions as separate commits. Right now it yields 3-5 commits per issue. Commits before rebase are saved in "archive/before-big-rebase" branch.

To consider: one commit per issue. After the issue is released intermediate states are not really interesting (unlike code). The only problem is exact contributions (patches) are lost.

Options to preserve contributions:

• State in the article (as done currently)
• Use Co-authored-by (GitHub specific?)
• Preserve commits in merged branches
• Preserve commits in master (current)

Git workflow has mostly stabilized but I'll keep this open until I do a few more planned things.
