[TriLUG] tab completion behavior changes with recent Ubuntu

[Pete Soper via TriLUG]

No worries. You're absolutely right that ~ is a lot shorter than $HOME.

But $XYZ/(tab) does exactly the same thing, adding a '\' in front of the 
dollar sign. I'd like to put a silver bullet through that aspect of my 
Linux configuration, recompile the "improved" code after "unimproving 
it", or whatever is necessary to escape this because my fingers can't 
seem to avoid using the tab key and I use lots of other env vars for 
pathnames besides $HOME.
