[Bug-readline] Bug: horizontal-scroll-mode on

[Devin Homan]

There seems to be a bug in sys-libs/readline.

In my .inputrc file, when I have

Code:

set horizontal-scroll-mode on

History tab completion (that is Ctrl-r <some text> [tab]) does not flow the text correctly.
So for example, if I have

Code:

eix readline

in my history and do "Ctrl-r l [tab]", I get

Code:

eix read lineline

.
Pressing enter issues the "eix readline" command.

I have been able to reproduce this on AMD_64 running Gentoo with readline versions 6.2_p5-r1, 5.2_p14, and 4.3_p5,
on Intel x86 running Gentoo with readline 6.2_p1, and on Arm v7 running Ubuntu with readline version 6.3.
