Whee.  Can you provide a backtrace?  (Please load tramp.el, not

Yes, is your Emacs checkout really really fresh?  I changed
dired-insert-directory to abstain from passing "--dired" for remote
files in a really recent version of Emacs.

(Oh, but I also made a change in Tramp, and without that change, it
doesn't work.  So I need to update the Tramp version in Emacs, first.)

It is really difficult.  Tramp uses tramp-shell-prompt-pattern to
grok shell prompts, and if you set that to match your ANSI escapes,
then you should be fine.

Another alternative is to set PS1 to something without ANSI escapes
if $TERM is "dumb".  You can't expect that kind of terminal to
understand the escapes anyway, so this change should be safe.

Hm.  I think that Emacs does "exec /bin/sh" after "sudo -u root -s".
Is this correct?  Then there is no problem.

Thanks for the heads-up.  As you imagine, I often hear reports of
Tramp *not* working, which can get frustrating from time to time.
