Bash Version: 4.3
Patch Level: 30
Release Status: release

Description:
        When using multiline prompt and entering a long command, the part
which doesn't fit and should be moved to a
new line is actually move to the beginning of the same line which makes the
command unreadable.

Repeat-By:
        1. Set e.g. PS1="\n\[\033[01;address@hidden;34m\]
\w\[\033[01;33m\]\n\n\033[01;31m\]-------------> \[\e[0m\]"
        2. Type a command longer than one line.

Fix:
        Expected behaviour is that the part which doesn't fit will be moved
to a new line, what happens when
        the prompt is one line long.
