Subject: 28.0.50; Problem in dired with symbolic links to Tramp-syntax files
Date: Tue, 11 May 2021 15:22:59 +0200

Apparently dired passes symlinks to Tramp in unfortunate ways.

For instance:

(cd /tmp; ln -s /sudo:root <at> localhost:/tmp/foo bar)
emacs -Q /tmp/

will infloop asking for a password -- `C-g' will break, but it'll just
ask again apparently forever, and you have to kill Emacs to get out of
the loop.

(cd /tmp; ln -s /sudo:root <at> nosuchhost:/tmp/foo bar)
emacs -Q /tmp/

won't even give you a prompt, but won't display anything -- hanging
while resolving the "nosuchhost" name?

I haven't tried to debug either case.
