+ - TENTATIVE: fix read_token_word to reduce the amount of buffer space
+ required to hold the translated and double-quoted value of $"..."
+ strings. Report and fix from Michael Witten <mfwitten@gmail.com>
+ - change code around got_character and got_escaped_character labels to
+ make sure that we call RESIZE_MALLOCED_BUFFER before adding the
+ CTLESC before a CTLESC or CTLNUL, and before adding the character if
+ we're not adding a CTLESC. Report and fix from
+ Michael Witten <mfwitten@gmail.com>
+
+subst.c
+ - new param flags value, PF_ASSIGNRHS, mirrors W_ASSIGNRHS, noting that
+ parameter expansion is on rhs of assignment statement. That inhibits
+ word splitting
+ - change param_expand to call string_list_dollar_at with quoted == 1
+ if PF_ASSIGNRHS is set, so it will quote IFS characters in the
+ positional parameter before separating them with the first char of
+ $IFS. This keeps the rhs from being split inappropriately. Fixes

+jobs.c
+ - add sentinel to wait_sigint_handler so it only sets wait_sigint_received
+ if waiting_for_child is non-zero; otherwise, it restores the old
+ SIGINT handler and sends itself the SIGINT
+ - set waiting_for_child around the calls to waitchld that use it to
+ synchronously wait for a process
+ - change logic that decides whether or not the child process blocked
+ or handled SIGINT based on whether or not waitpid returns -1/EINTR
+ and the shell receives a SIGINT and the child does not exit. If
+ the child later exits due to SIGINT, cancel the assumoption that it
+ was handled
+ - instead of testing whether or not the child exited due to SIGINT
+ when deciding whether the shell should act on a SIGINT it received
+ while waiting, test whether or not we think the child caught
+ SIGINT. If it did, we let it go (unless the shell has it trapped);
+ if it did not catch it, the shell acts on the SIGINT. Fix from

+execute_cmd.c
+ - add a couple of QUIT; calls to execute_disk_command and
+ execute_simple_command to improve responsiveness to interrupts

+
+input.c
+ - rearrange getc_with_restart so that the return values from read()
+ are handled right
+
+parse.y
+ - don't need to set terminate_immediately in yy_stream_get, since
+ getc_with_restart checks for terminating signals itself
+ - since readline returns READERR on SIGHUP or SIGTERM, don't need
+ to set terminate_immediately. Still doesn't handle other

+
+bashline.c
+ - new function, bash_event_hook, for rl_event_hook. Just checks for
+ terminating signals and acts on them using CHECK_TERMSIG.
+ - set rl_event_hook to bash_event_hook
+

+ - take out setting terminate_immediately; add calls to CHECK_TERMSIG

+ expansions, after resetting expanding_redir to 0, call sv_ifs
+ again to make sure the cached IFS values are set from any
+ assignments in the temporary environment. We force executing_builtin
