I've been trying this, I like the separation between checking whether
a relayout is needed or not and the actual relayout.

There's one problem with `buffer-list-update-hook` though, it gets
called (multiple times) even wen the buffer list is not changed, e.g.,
simply by clicking in the buffer. Is this the expected behaviour?

Besides this, if there's no way to get rid of false positives in event
handling (i.e., a relayout is triggered but no actual change happened)
I guess I need a way to decide if a relayout is *really* needed. A
naive way would be saving the current window and buffer but I'm not
sure if we can do better.

Also, oddly enough, `pre-redisplay-function` is never called on macOS
(Emacs 26.1)...
