 	- _rl_dispatch_subseq, _rl_subseq_result: don't call _rl_unget_char
 	  if we're currently reading from a macro; call _rl_prev_macro_key
 	  instead.  Fixes bug reported by Clark Wang <clark.wang@oracle.com>

+builtins/evalstring.c
+	- evalstring(): new function, wrapper around parse_and_execute.
+	  make sure we handle cases where parse_and_execute can call `return'
+	  and short-circuit without cleaning up properly.  We call
+	  parse_and_execute_cleanup() then jump to the previous-saved return
+	  location
+
+builtins/common.h
+	- extern declaration for evalstring()
+
+builtins/eval.def
+	- eval_builtin: make sure we handle `eval " ... return"' in contexts
+	  where `return' is valid by calling evalstring().  Fixes bug with
+	  `eval return' in sourced files reported by Clark Wang

+
+trap.c
+	- run_pending_traps: call evalstring instead of parse_and_execute.
+	  XXX - still needs to handle saving and restoring token state in the
+	  presence of `return'; could use unwind_protects for that
+
+builtins/mapfile.def
+	- run_callback: call evalstring instead of parse_and_execute

+bashline.c
+	- bash_filename_stat_hook: make sure we don't free local_dirname
+	  before using it to canonicalize any expanded filename.  Make sure
+	  it always points to *dirname and only free it if we're replacing
+	  it.
+
+lib/readline/complete.c
+	- append_to_match: make sure we call rl_filename_stat_hook with
+	  newly-allocated memory to avoid problems with freeing it twice

+variables.c,config-top.h
+	- if ARRAY_EXPORT is defined to 1 when variables.c is compiled, the
+	  code that allows indexed arrays to be exported is enabled and
+	  included

+shell.c
+	- call start_debugger from main() only if dollar_vars[1] != 0 (close
+	  enough to a non-interactive shell, since we can be interactive with
+	  -i while running a shell script).  Fixes oddity reported by
+	  Techlive Zheng <techlivezheng@gmail.com>
