Are you sure? Ctrl-L appears to just call redraw_later, and I didn't
fully trace the call tree, but redraw_later seems to end up calling
FOR_ALL_WINDOWS...redraw_win_later, which would end up calling
redrawWinline (which does something with folds), eventually... yes?

All I know is that every time I've noticed an improper fold, I've hit
Ctrl-L to correct the problem.

But again, I don't use fdm=expr. So, maybe whatever mechanism marks a
fold as invalid doesn't use the same logic when fdm=syntax.
