Update to 6.0:

This is a terse description of the new features added to readline-6.0 since
the release of readline-5.2.

1.  New Features in Readline

a.  A new variable, rl_sort_completion_matches; allows applications to inhibit
    match list sorting (but beware: some things don't work right if
    applications do this).

b.  A new variable, rl_completion_invoking_key; allows applications to discover
    the key that invoked rl_complete or rl_menu_complete.

c.  The functions rl_block_sigint and rl_release_sigint are now public and
    available to calling applications who want to protect critical sections
    (like redisplay).

d.  The functions rl_save_state and rl_restore_state are now public and
    available to calling applications; documented rest of readline's state
    flag values.

e.  A new user-settable variable, `history-size', allows setting the maximum
    number of entries in the history list.

f.  There is a new implementation of menu completion, with several improvements
    over the old; the most notable improvement is a better `completions
    browsing' mode.

g.  The menu completion code now uses the rl_menu_completion_entry_function
    variable, allowing applications to provide their own menu completion
    generators.

h.  There is support for replacing a prefix  of a pathname with a `...' when
    displaying possible completions.  This is controllable by setting the
    `completion-prefix-display-length' variable.  Matches with a common prefix
    longer than this value have the common prefix replaced with `...'.

i.  There is a new `revert-all-at-newline' variable.  If enabled, readline will
    undo all outstanding changes to all history lines when `accept-line' is
    executed.

-3 patches from Debian rolled into one:
-
-http://lists.gnu.org/archive/html/bug-bash/2006-11/msg00017.html
-
-Bug-Description:
-
-In some cases, code that is intended to be used in the presence of multibyte
-characters is called when no such characters are present, leading to incorrect
-display position calculations and incorrect redisplay.
-
-http://lists.gnu.org/archive/html/bug-readline/2007-01/msg00002.html
-
-Bug-Description:
-
-Readline neglects to reallocate the array it uses to keep track of wrapped
-screen lines when increasing its size.  This will eventually result in
-segmentation faults when given sufficiently long input.
-
-http://lists.gnu.org/archive/html/bug-bash/2007-02/msg00054.html
-
-Bug-Description:
-
-When moving the cursor, bash sometimes misplaces the cursor when the prompt
-contains two or more multibyte characters.  The particular circumstance that
-uncovered the problem was having the (multibyte) current directory name in
-the prompt string.
