This not anything new.  <tab> has always done this, since before there was 
even Linux.  It only adds the space if/when it only has one completion.  If 
there are multiple completions, then the completion stops just at the point of 
ambiguity.

Probably.  *I* don't use bash -- I use tcsh, which is a little different.
