I upgraded to the latest trisquel release and noted this problem: In a terminal, whether typing to the bash prompt or to my program that calls readline, if I use ctrl-R and a text fragment, it finds and displays previous input normally, but when I use a cursor key the line goes blank. I can move the cursor over the line and edit the text; I just can't see what I'm doing. In an x-term the cursor key makes the line be re-displayed, moved a few characters left, without erasing the previous display, so that a few spurious characters are shown on the end. These problems do not occur with input lines that are recalled by using the UP-arrow key. Here's a workaround: recall a line by using ctrl-R, then use UP-arrow and DN-arrow to get a 'normal' display of that line which can then be edited without problems.
readline version 6.3 you ask for the 'release status'. Where do I find that? machine and OS: this is output of uname -a Linux user-ThinkPad-X60 3.13.0-51-generic #84+7.0trisquel2 SMP Thu Apr 30 10:28:47 UTC 2015 i686 i686 i686 GNU/Linux
