Thanks so much for working on the e2fsprogs documentation! It is an
often an underappreciated work, and I'm glad to have someone working
to improve the documentation.

The maint branch corresponds to the 1.43.x release series, and the
master and next branches present what will (soon) become the 1.44(.x)
release. There will be at least one more 1.43.x release before I
release 1.44, so it's not that of an issue.
I can handle trying to apply these patches to the maint branch,
pulling out the feature improvements that only appear in the master
branch and applying that in a separate patch for the master branch.
But in the future, it would be preferable for bug fixes and doc fixes
to be done against the maint branch (if applicable). The master/next
branch will get fixes via git merges.
Cheers,
- Ted
