[IPython-dev] Bug in pysh?

Hi,

I just ran into this little problem with pysh-0.6.5

   |35> ls -l | tr -s [:blank:] | cut -d' ' -f 5-5
[...]

This works fine.  Unfortunately, this does not:

   $$a = ls -l | tr -s [:blank:] | cut -d' ' -f 5-5
   cut: the delimiter must be a single character
   Try `cut --help' for more information.

To get this to work I need to escape the quotes like so:

   $$a = ls -l | tr -s [:blank:] | cut -d\' \' -f 5-5

I was surprised at first but realized it was the quoting.  So if this
is fixable, that would be cool.  If not perhaps it could be documented
somewhere?

Thanks.
cheers,
prabhu
