1This is a terse description of the new features added to readline-5.1 since
2the release of readline-5.0.
3
41.  New Features in Readline
5
6a.  The key sequence sent by the keypad `delete' key is now automatically   
7    bound to delete-char.
8
9b.  A negative argument to menu-complete now cycles backward through the
10    completion list.
11
12c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
13    readline will bind the terminal special characters to their readline
14    equivalents when it's called (on by default).
15
16d.  New bindable command: vi-rubout.  Saves deleted text for possible  
17    reinsertion, as with any vi-mode `text modification' command; `X' is bound
18    to this in vi command mode.
19
20e.  If the rl_completion_query_items is set to a value < 0, readline never
21    asks the user whether or not to view the possible completions.
22
23f.  New application-callable auxiliary function, rl_variable_value, returns
24    a string corresponding to a readline variable's value.
25
26g.  When parsing inputrc files and variable binding commands, the parser
27    strips trailing whitespace from values assigned to boolean variables
28    before checking them.
29
30h.  A new external application-controllable variable that allows the LINES
31    and COLUMNS environment variables to set the window size regardless of
32    what the kernel returns.
