New Features in readline-8.1 since the release of readline-8.0
a. If a second consecutive completion attempt produces matches where the first
   did not, treat it as a new completion attempt and insert a match as
   appropriate.
b. Bracketed paste mode works in more places: incremental search strings, vi
   overstrike mode, character search, and reading numeric arguments.
c. Readline automatically switches to horizontal scrolling if the terminal has
   only one line.
d. Unbinding all key sequences bound to a particular readline function now
   descends into keymaps for multi-key sequences.
e. rl-clear-display: new bindable command that clears the screen and, if
   possible, the scrollback buffer (bound to emacs mode M-C-l by default).
f. New active mark and face feature: when enabled, it will highlight the text
   inserted by a bracketed paste (the `active region') and the text found by
   incremental and non-incremental history searches. This is tied to bracketed
   paste and can be disabled by turning off bracketed paste.
g. Readline sets the mark in several additional commands.
h. Bracketed paste mode is enabled by default. There is a configure-time
   option (--enable-bracketed-paste-default) to set the default to on or off.
i. Readline tries to take advantage of the more regular structure of UTF-8
   characters to identify the beginning and end of characters when moving
   through the line buffer.
j. The bindable operate-and-get-next command (and its default bindings) are
   now part of readline instead of a bash-specific addition.
k. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
