a. Fixed a bug that caused the unconverted filename to be added to the list of
completions when the application specified filename conversion functions.
b. Fixed a bug that caused the wrong filename to be passed to opendir when the
application has specified a filename dequoting function.
c. Fixed a bug when repeating a character search in vi mode in the case where
there was no search to repeat.
d. When show-all-if-ambiguous is set, the completion routines no longer insert
a common match prefix that is shorter than the text being completed.
e. The full set of vi editing commands may now be used in callback mode.
dimensions while running in `no-echo' mode.
h. Fixed a bug that caused readline to dump core if an application called
rl_prep_terminal without setting rl_instream.
i. Fixed a bug that caused meta-prefixed characters bound to incremental
search forward or backward to not be recognized if they were typed
subsequently.
j. The incremental search code treats key sequences that map to the same
functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
k. Fixed a bug in menu-complete that caused it to misbehave with large
negative argument.
l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
at the end of the line.
m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
as if it were a negative argument.
n. Fixed a bug that caused directory names in words to be completed to not
be dequoted correctly.
New Features
a. The history library does not try to write the history filename in the
current directory if $HOME is unset. This closes a potential security
problem if the application does not specify a history filename.
b. New bindable variable `completion-display-width' to set the number of
columns used when displaying completions.
c. New bindable variable `completion-case-map' to cause case-insensitive
completion to treat `-' and `_' as identical.
d. There are new bindable vi-mode command names to avoid readline's case-
insensitive matching not allowing them to be bound separately.
e. New bindable variable `menu-complete-display-prefix' causes the menu
completion code to display the common prefix of the possible completions
before cycling through the list, instead of after.
