This document details the changes between this version, bash-4.3-beta2, and the
previous version, bash-4.3-beta.
1. Changes to Bash
a. Fixed a bug that caused assignment to an unset variable using a negative
subscript to result in a segmentation fault.
b. Fixed a bug that caused assignment to a string variable using a negative
subscript to use the incorrect index.
c. Fixed a bug that caused some strings to be interpreted as invalid
extended globbing expressions when used with the help builtin.
d. Fixed a bug that caused an attempt to trap a signal whose disposition
cannot be changed to reference uninitialized memory.
e. Command completion now skips assignment statements preceding a command
name and completes the command.
f. Fixed a bug that caused `compgen -f' in a non-interactive shell to dump
core under certain circumstances.
g. Fixed a bug that caused the `read -N' to misbehave when the input stream
contains 0xff.
2. Changes to Readline
a. Changed message when an incremental search fails to include "failed" in
the prompt and display the entire search string instead of just the last
matching portion.
b. Fixed a bug that caused an arrow key typed to an incremental search prompt
to process the key sequence incorrectly.
3. New Features in Bash
a. The help builtin now attempts substring matching (as it did through
bash-4.2) if exact string matching fails.
b. The fc builtin now interprets -0 as the current command line.
c. Completing directory names containing shell variables now adds a trailing
slash if the expanded result is a directory.
4. New Features in Readline
a. rl_change_environment: new application-settable variable that controls
whether or not Readline modifies the environment (currently readline
modifies only LINES and COLUMNS).
