Broken eshell tab completion (pcomplete) over ssh

Broken eshell tab completion (pcomplete) over ssh

[pinkiesOut]

Although tab completion in eshell works on my local system, pressing tab when connected to another machine over ssh results in the insertion of a literal tab character. Running pcomplete manually with M-x produces the same result, confirming that the function is properly bound to my tab key. Some friendly folks at #emacs point out that tab completion in eshell should just work over ssh.

Oddly, I do not have this problem when connecting to the same server using term or ansi-term mode. Does anyone have an idea of what might be breaking this functionality? 

For the record, I am running emacs 23.3.50.1, yet I see a similar unanswered question regarding eshell in emacs 24.0.94 at the following URL:

Thanks

It doesn't know which program you're running.  It simply assumes
a command-line program, which is true --- you are talking to your
login shell.  Since Eshell doesn't have a `char-mode' like term
does, it sends your input line by line, so it ends up as a
literal tab.

Use `cd /ssh:user@host:'.

XeCycle,

This works. Thanks for the tip!
