won't usage of this (without an equivalent to bash's \[ \]) mess up
the prompt width calculation?
maybe something like...

@item @var{\[}
Begins a sequence of non-printing characters.
@item @var{\]}
Ends a sequence of non-printing characters.

def _prompt_nonprinting_begin(attr):
   "Begins a sequence of non-printing characters."
   return '\001'

def _prompt_nonprinting_end(attr):
   "Ends a sequence of non-printing characters."
   return '\002'
