Subject: Fix misleading "File exists, but cannot be read" in browse-url-emacs
X-Git-Tag: emacs-29.0.90~1616^2~646

Fix misleading "File exists, but cannot be read" in browse-url-emacs

* src/fileio.c (Finsert_file_contents): Don't signal an error
about not being able to open the file when we're fetching things
via handlers -- in that case, modtime isn't necessarily set, and
if there's a handler, it should take care of this (bug#42431).
