Status update:
The upstream maintainer has been alerted to this issue, and Thomas Dickey has
provided a more detailed evaluation of the problem:
http://lists.gnu.org/archive/html/bug-bash/2005-07/msg00112.html. There is
apparently some interaction between readline and ncurses insert mode, where
readline made some invalid assumptions about invisible characters. And the
code in readline/display.c is HAIRY - Hans' proposed hack that has been posted
to this list is not a proper fix, just a workaround that hides the worst of the
bug.
I'm still working on getting a bash-3.0-8 ready for release (mainly for the
tilde-expansion bug and the missing .info file). If upstream provides a patch
for the prompt bug in a timely manner, it will be included too.
