+execute_cmd.c

+	  keeping `continuing' set to 1.  Reported by Dan Douglas

+subst.c,command.h
+	- move the PF_ constants to command.h so other files can see them, now
+	  that PF_ASSIGNRHS has meaning to string_list_dollar_at
+
+arrayfunc.h
+	- AV_ASSIGNRHS: new flag, indicate that ${a[@]} is being expanded on
+	  the RHS of an assignment statement
+
+arrayfunc.c
+	- array_value_internal: if AV_ASSIGNRHS passed for ${a[@]}, pass
+	  PF_ASSIGNRHS to string_list_dollar_at to support args separated by
+	  spaces even if $IFS does not have the default value.  Reported by
+	  Dan Douglas <ormaaj@gmail.com>
+
+subst.c
+	- string_list_dollar_at: if FLAGS argument includes PF_ASSIGNRHS, obey
+	  rules for $@ on the RHS of an assignment statement: expand to
+	  postitional parameters separated by spaces no matter what the first
+	  character of $IFS is.  Reported by Dan Douglas <ormaaj@gmail.com>
+	- parameter_brace_expand_word: pass AV_ASSIGNRHS as flags value to
+	  array_value if PF_ASSIGNRHS is set and we are expanding an array
+	  variable subscripted by @ or *
+	- param_expand: pass pflags to string_list_dollar_at in case it contains
+	  PF_ASSIGNRHS
+	- expand_word_internal: if we have an assignment statement argument to
+	  a declaration builtin (W_ASSIGNARG), turn on W_ASSIGNRHS when we see
+	  the `=' to enable special $@ behavior
+	- expand_word_internal: if W_ASSIGNARG enabled in word flags, pass that
+	  flag and W_ASSIGNRHS to recursive call to expand_word_internal when
+	  expanding double-quoted string; handles "$@" when IFS is not the
+	  default value and word splitting will not be performed
+
+subst.c
+	- expand_word_internal: change case that handles '' (single-quoted
+	  empty string) to only discard it if we will not be performing word
+	  splitting (W_NOSPLIT|W_NOSPLIT2), since we need to add a quoted null
+	  argument if the subsequent characters will cause word splitting.
+	  This is how "" (double-quoted empty string) is handled after a bug
+	  fix back in August 2010.  Reported by Grisha Levit

+subst.c
+	- param_expand: change fix from 6/23 (expanding $* in a context where
+	  word splitting is not performed) to make sure that $* expands to
+	  something before trying to quote the string.  Bug and fix from
+	  Andreas Schwab <schwab@suse.de>
+
+lib/readline/bind.c
+	- _rl_get_string_variable_value: fix a cut-and-paste error that caused
+	  the emacs mode string to be displayed for both vi insert and command
+	  mode strings.  Report and fix from Steve Jones <sjml@slohj.org>

+lib/readline/display.c
+	- update_line: we can't use PROMPT_ENDING_INDEX unless we're testing
+	  against _rl_last_c_pos; if we are testing buffer indices, we need to
+	  use prompt_last_invisible directly.  Fixes mode string redisplay issue
+	  with short prompt strings reported by Steve Jones <sjml@slohj.org>

+nojobs.c
+	- without_job_control: new function, resets child state that's eventually
+	  used to decide whether or not to wait_for children
+
+execute_cmd.c
+	- initialize_subshell: call without_job_control in both the JOB_CONTROL and
+	  no job control paths so we can reset the state in subshells that will not
+	  cause them to wait_for children inappropriately.  Fixes bug reported by
+	  Dan Cross <crossd@gmail.com>

+
+bashline.c
+	- command_word_completion_function: if direxpand is set, make sure to
+	  run hint_text through bash_directory_completion_hook, since
+	  readline will do that and we want to be able to match the results
+	  readline returns.  Fixes bug reported by Pat Somaru

+command.h

+	- PF_COMPLETE: new flags value for param_expand
+
+subst.h
+	- SX_STRIPDQ: new flag, used for string_extract_double_quoted
+
+bashline.c
+	- bash_filename_stat_hook,bash_directory_completion_hook: pass W_COMPLETE
+	  flag to expand_prompt_string
+
+subst.c
+	- expand_word_internal: if W_COMPLETE in word->flags, pass PF_COMPLETE
+	  to param_expand
+	- param_expand: if PF_COMPLETE in pflags, pass SX_COMPLETE to
+	  extract_command_subst.  This allows `"$(echo ~/' to perform
+	  completion successfully
+	- string_extract_double_quoted: turn third argument into a flags arg,
+	  old STRIPDQ is now set if flags&SX_STRIPDQ
+	- string_extract_double_quoted: changed callers, if third argument was
+	  1, pass SX_STRIPDQ instead
+	- expand_word_internal: if W_COMPLETE in word->flags, pass SX_COMPLETE
+	  in flags to string_extract_double_quoted for case '"'
+	- string_extract_double_quoted: if SX_COMPLETE in flags, pass it to
+	  extract_command_subst
+	- expand_word_internal: if W_COMPLETE in word->flags, make sure W_COMPLETE
+	  is in temp word passed to recursive call to expand_word_internal to
+	  expand double-quoted string.  Fixes bug reported by John Passaro
