After this update, octave-gui (5.2.0) in x-window shows strange string
at the prompt.
>> undecodable token: \001b(hex)[?2004l
undecodable token: \001b(hex)[?2004h
To reproduce this,
1) Start X with 'run XWin -multiwindow'
2) Start octave-gui with 'env DISPLAY=:0 octave --force-gui'
Does libreadline7 (8.1) break compatibility with old one?
Reverting libreadline7 to 7.0.3-3 solves the issue.
Setting
set enable-bracketed-paste off
in ~/.inputrc also solves the problem.
This may be a problem of octave side.

Any idea?
