Essentially a bug in the redisplay logic. It affected Bash, mysql&amp;#x2F;psql, Python, etc.&lt;p&gt;After having suffered from this for some years, last year that annoyed me enough to start digging into readline to figure out what was causing it. In the end, that prompted Chet Ramey to come up with a fix which looks like it is now being released!&lt;p&gt;I promised myself that when this one was fixed, I&amp;#x27;d look into why most readline shells can go nuts when you resize them - somehow they don&amp;#x27;t always discover that the line width has changed.</text><parent_chain></parent_chain></comment><story><title>Bash 4.4 released</title><url>http://lists.gnu.org/archive/html/bug-bash/2016-09/msg00018.html</url></story>

New prompt string: PS0.  Expanded and displayed by interactive
        shells after reading a complete command but before executing it.
&lt;/code&gt;&lt;/pre&gt;
I currently use my PS1 for a lot of dirty things that would have their place in such a PS0 :).&lt;p&gt;Now, I just have to wait until Bash 4.4 lands in Debian…</text><parent_chain></parent_chain></comment><story><title>Bash 4.4 released</title><url>http://lists.gnu.org/archive/html/bug-bash/2016-09/msg00018.html</url></story>
