bug#57684: locked narrowing breaks existing code without an apparent way to repair

[Paul Pogonyshev]

By the way, today Emacs 29 hung in Magit blaming for me, with C-g doing nothing. Grepping Magit sources suggest it uses the "save-restriction - temporarily widen" more than ten times in various places, 3 of them when blaming. Cannot say for sure that was it, but all the outer symptoms are identical with the hangs in Logview.

I really think there must be a way to "widen no matter which locks are installed" - a lot of code seems to depend on that.

I don't know yet.  Not "that much" I think, but there are a number of
things that need to be fixed/improved.
