[PATCH] bash.1: document /etc/inputrc

From: Greg Price
Subject: [PATCH] bash.1: document /etc/inputrc
Date: Sun, 3 May 2020 20:01:13 -0700

This patch amends bash.1 to explain the sequence of places the
inputrc is found (INPUTRC, ~/.inputrc, /etc/inputrc) in the same
way as in readline.3 and bash.info.

The existing text had me puzzled for a bit, as it seemed to say
that /etc/inputrc wasn't part of Bash's own behavior, even though
I knew I'd seen it take effect when I didn't have a ~/.inputrc.
I spent a few minutes searching to see where in my dotfiles or in
/etc/ the convention of /etc/inputrc might have come from, before
finding it in a grep of the Bash source tree. :-)  Hopefully this
patch can prevent the same confusion for others.

Thanks, regards,

 When a program which uses the readline library starts up, the
 initialization file is read, and the key bindings and variables
 are set.
