[Trisquel-users] readline goes invisible after R

[mcconnau]

After upgrade to version 7, I am having trouble with the R function in  
readline (search for previous input containing a given string). It finds the  
previous input and presents that, but when I push one of the cursor keys, the  
line goes blank. The cursor will move over that blank space and I can type  
input and have the edited lines show up in the history. But editing 'blind'  
is not a satisfactory experience.
This is the behavior in a TTY. In an xterm, the cursor key causes the line to  
be re-printed starting a few character cells to the left of where it was at  
first, and that number of character cells at the end does not get erased. I  
can edit that line normally (ignoring those extra characters on the screen).
My readline library is libreadline.so.6.3 dated 18 Mar 28  2014
