2.0 format became default years and years ago, and xmonad development
has been stable/stagnant for as long. They can upgrade their own repo
if they want to send a patch from however long ago (which seems
unlikely since it's bad practice to keep a fork private for a long

You can scp a local version of the original repo, if you are worried
about irreversibility. As for diff - well yeah, of course they differ,
that's the point. 'Some such things'? Do you really think the Darcs
team would've switched to 2.0 format, released it, set it as default,
continue to release for years and years, and publicly recommend using
it as default if those diffs were not either irrelevant or

I mean honestly. That just reads as excuse-making.

For long-lived private branches, better handling of conflicts is
important... So which is it, #1 or #4? Are there long-lived private
patches per #1 in which case #4 is wrong, or are there not, in which
case #4 is right but #1 wrong?
