bug#57800: TRAMP insert-file-contents now fails for regions

[Paul Pogonyshev]

Hm, now I cannot reproduce this anymore. But today I got this bug,

recompiled Emacs from Git and the bug was still there. Right now I

tested Emacs 28 in case I managed to switch them accidentally, but

no, also not there.

So, either I have mixed something up, or this depends on some

volatile state in TRAMP, e.g. its cache.

I guess you can close the bug.

I tried this recipe with the current trunk, and things worked fine for
me.

Is it possible that you have an old version of tramp somewhere in your
load path?  I seem to vaguely recall that insert-file-contents +
start/end was something that was fixed sometime last year.
