+	- quote_escapes_internal: refactored quote_escapes into a function
+	  that takes an additional flag saying whether or not we are going
+	  to split the result. If we are not, and CTLESC is in IFS, we quote
+	  the CTLESC (ditto for CTLNUL) to prevent it being removed when the
+	  string is dequoted.
+	- quote_escapes: call quote_escapes_internal with FLAGS == 0
+	- quote_rhs: new function, calls quote_escapes with FLAGS == PF_NOSPLIT2
+	  so that a CTLESC will be quoted if CTLESC is in $IFS
+	- parameter_brace_expand_word: call quote_rhs on the value of a variable
+	  if PFLAGS includes PF_ASSIGNRHS, indicating that we will not be
+	  splitting the word, but we will be dequoting it. Fixes bug reported
+	  by Martijn Dekker <martijn@inlv.org>
+	- param_expand: same change as for parameter_brace_expand_word
+
+execute_cmd.c
+	- execute_in_subshell: if we are running a trap (running_trap > 0),
+	  turn off the SIG_INPROGRESS and SIG_CHANGED flags for that signal
+	  by calling run_trap_cleanup and reset running_trap to 0 (watch the
+	  second part!)
