+lib/readline/readline.h
+	- RL_STATE_CHARSEARCH: new state, for vi mode character search.  Was

+lib/readline/vi_mode.c
+	- rl_domove_motion_callback: split into two functions, remaining code
+	  after _rl_dispatch call goes into new function
+	  _rl_vi_domove_motion_cleanup
+	- rl_vi_char_search: set RL_STATE_CHARSEARCH
+	- rl_vi_char_search: sets `i2' member of callback data to the key used
+	  to invoke the char search
+	- _rl_vi_callback_char_search: unset RL_STATE_CHARSEARCH after reading
+	  the character to find
+	- _rl_vi_domove_motion_cleanup: make sure RL_STATE_VIMOTION is unset in
+	  all cases where this function returns
+	- _rl_vi_domove_motion_cleanup: use `end' member of vi motion context
+	  as value of rl_end to restore after adding blank at end of line in
+	  rl_domove_motion_callback; avoids need to keep `old_end' and somehow
+	  pass it between the two functions
+
+lib/readline/rlprivate.h

+lib/readline/callback.c
+	- rl_callback_read_char: handle RL_STATE_CHARSEARCH, including case
+	  where char search is vi motion command for d/c/y/m and RL_STATE_VIMOTION
+	  is set when this is called.  Last of set of fixes for bug reported
+	  by Carlos Pita <carlosjosepita@gmail.com> with vi-mode `dty' command
+	  in callback mode

+lib/sh/shquote.c
+	- sh_double_quote: since all uses of the return value from this function
+	  are for display and not subject to subsequent expansion, we don't
+	  need to protect CTLESC and CTLNUL with CTLESC.  Bug report and fix
+	  from isabella parakiss <izaberina@gmail.com>

+parse.y

+	  and CTLNUL with CTLESC, even if they are not coming out of one of

+subst.c
+	- make_internal_declare: fixed memory leak; make_internal_declare should
+	  free the memory it allocates to construct the word list.  From Red

+lib/readline/readline.c
+	- _rl_dispatch_subseq: when checking whether an ESC in vi insert mode
+	  should be treated as part of a key sequence or as a single char,
+	  make sure we are getting input from the keyboard before we check
+	  _rl_input_queued().  If we are getting input from a macro, this
+	  causes a needless delay.  Report from Carlos Pita
