#   termwide prompt
#      by Giles - created 2 November 98
#                 last modified 9 November 98
#
#   The idea here is to have the upper line of this two line prompt 
#   always be the width of your term.  Do this by calculating the
#   width of the text elements, and putting in fill as appropriate
#   or right-truncating $PWD.
#
#   - needs a lot of refinement, but it works
#   - host doesn't need to be figured out every time: that's a 
#     constant
#   - what about username?  could change?
#   - text vars generated by prompt_command can't be locals,
#     because they have to go to PS1.
