Agreed (about replicating behavior of command line), but this means you
*don't* need to manually escape spaces.  Try:

cd /tmp
date > hello\ world

As you'll see, bash expands the 'hel as 'hello\ world', and you correctly
cat the file.

Note:  I haven't looked carefully at the ShellPrompt module, but I wonder
if it could call bash to do the completions, like DirectoryPrompt does
(which does properly handle directories with spaces in them).
Unfortunately, it seems to be hard to get the full power of the bash
programmable completions framework out of bash, which seems a poor design
to me.  :(
