[Bug-readline] [6.3] horizontal-scroll always on

[Dario Niedermann]

Hello!

Reporting to the list about some unexpected behaviour I'm seeing in GNU
Readline 6.3: option 'horizontal-scroll-mode' seems to be always on,
even when it's verifiably turned off. I'm using said Readline version
from within Bash 4.3.30(1)-release. Bash is compiled from source, with
option '--with-installed-readline'. Here's a slightly edited GNU Screen
"hardcopy" showing what I see:


-----BEGIN HARDCOPY-----
+0:~$ ldd /usr/local/bin/bash
        linux-vdso.so.1 (0x00007fff4632b000)
        libreadline.so.6 => /opt/pkg/lib/libreadline.so.6 (0x00007fe0264aa000)

+0:~$ !$
/usr/local/bin/bash
[...]
+0:~$ bind -V |grep scroll
horizontal-scroll-mode is set to `off'
<tal-scroll-mode is off, so if I start typing a very long
-----END HARDCOPY-----


The last line is where I'm typing, and it still scrolls when exceeding a
certain length.

I attach my inputrc files, in case you want to test the setup.

Thanks for your attention,
