AFAIR, the first time I heard about the `min-margins' parameter was when I
looked at the release notes of Emacs 25 after it came out. I don't remember why
I didn't try it out immediately, but after that, I probably forgot about it,
until a bug report I got a week ago.

Paul Rankin did add `min-margins' to his `olivetti' package, but he didn't
remove the pre-25 workaround that uses the `split-window' window parameter, so
the problem probably never showed up.

OK, so yet another way of doing things. :-) Sounds like it would make my life a
little easier, though.

Feel free to let me know when you implement it. I don't normally follow
development that closely, but in this case I'd be interested to test the new way
of doing things before the official release.
