Many people are using Fedora 18, and I haven't seen any other complaint yet.

And? Tramp does not use shell-mode. Anyway, this prompt is hard enough
to parse. The Tramp manual gives you some hints how to avoid escape
sequences, when scripts are accessing your account from remote.

Maybe there was a pattern change in Tramp. As I said, I don't remember, but ...

Sorry, I don't use Fedore, and I don't understand what you have changed
via rpmbuild etc. Anyway, if I could see your complete prompt (including
escape sequence), I could try to adapt tramp-shell-prompt-pattern to
your needs. The example above is not sufficient, because it does not
expand user and host names, and alike.

Just run your test case with tramp-verbose 10. There will be traces like

--8<---------------cut here---------------start------------->8---
12:37:39.845362 tramp-accept-process-output (10) # 
#$
--8<---------------cut here---------------end--------------->8---

(#$ is my prompt). Send those lines as coded attachment, in order not to
loose escape sequences. I will analyze them.

You could send it directly to me, in order to avoid bit lossages.

Best regards, Michael.
