Bash Version: 3.0
Patch Level: 0
Release Status: release

Description:
It seems that when using multiline prompts in Bash 3.0 there is some sort of
issue with the terminal starting to wrap characters earlier, the longer the
previous lines of prompt the less width of terminal is available to type
commands in.

Repeat-By:
export PS1='123456789 123456789 123456789 123456789 123456789 123456789\n\$ '

Then just type, you should see it starting to wrap at about 20 cols in.

Fix:
Unknown, tried using prompts with \n\r or \r\n in instead of just \n doesn't
seem to fix it.
Also tried using " and ' quote types around the string that doesn't seem to
work either.
