Description Tony Finch 1999-09-27 04:40:00 UTC 
If you are using libreadline with a multiline prompt containing invisible
characters on the last line, then when the program receives SIGWINCH and
redraws the last line of the prompt it outputs spurious ^A and ^B
character(s).

Fix: I think the first patch is correct; the second one *might* catch more
cases, but requires a bit more work at run time. 

How-To-Repeat: run bash in an xterm
set PS1 to 'line one\n\[\e[1m\]line two\[\e[0m\] '
you will then have a two line prompt with invisible characters on the second line
change the size of the xterm; the second line will be bracketed with
a diamond-dither pair

This has been fixed in a more recent version of readline, so the PR
can be closed.

Tony.
