tramp (2.0.15); /multi:sudo:address@hidden:/ - Args out of range: [], 1

[Sacha Chua]

Using the tramp included in CVS Emacs, opening
/multi:sudo:address@hidden:/ results in "Args out of range: [], 1"

/multi:sudo:address@hidden:/var works, although I get the //DIRED// ... lines 
at the end.

Also, I had to set my PS1 to '$ ' in order to get it to even connect,
as my normal prompt has ANSI escape codes. =) Maybe this can get fixed
sometime. My user shell may not be bash, too, and sudo -u root -s
actually uses _my_ $SHELL, so you could probably unset that or set it
to whatever shell you prefer. (Or you could just set PS1...) Anyway,
I'm pretty sure you folks can figure it out.

Keep up the great work! Tramp is wonderful, and one of the things I
show off to the few people whom I haven't converted to Emacs yet. =)
