Yes, it works even in shell-mode. After a short delay the *Completions* 
buffer disappears.

Thanks, I'll try to find it if pcomplete is still insufficient.

Thanks! Now the examples above work. However there's a new problem:
1. I create a new shell.
2. I enter "ls pro", hit tab and get "ls projects".
3. After hitting enter and seeing the contents I type "ls pro" again.
4. Now, autocompletion doesn't work anymore, nothing happens.
So, somehow pcomplete seems to become corrupted. After its first 
autocompletion it can't autocomplete directories in the home directory any 
more. In addition pcomple sometimes hangs or is slow and I have to hit 
"C-g" to cancel it. 

I'm using
