bash & $PS1 (display error)

[Rolf Campbell]

I've noticed several display problems with bash and prompts.  Here's an
easy way to recreate one of them:

(I've marked the lines to alleviate the wrapping problem)

#line 1
PS1='$PWD> '
#line2
mkdir -p
/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp
/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp
#line3
cd
/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp
/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp

When I run this (whether it be in rxvt or in the NT console) I get a
prompt that looks like this:
/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp/tmp
/tmp/tmp/tmp/tmp/tmp/tmp/tmp(#1)
/tmp(#2)
/tmp/tmp/tmp/tmp/tmp>

I've marked the original new-lines.  (#1) in a correct wrap that
occurred at the edge of my display.  (#2) is an incorrect wrap that
happens for no obvious reason.

This only seems to happen if the path is wider than the display.
