+builtins/trap.def
+	- trap_builtin: if OP is `-' (revert), set the SIGINT signal handler
+	  to sigint_sighandler if the shell is interactive and sourcing a
+	  file (interactive_shell && sourcelevel) or running a trap
+	  (interactive_shell && running_trap) even if it's not currently
+	  interactive.  Report from Martijn Dekker <martijn@inlv.org>

+builtins/read.def

+	  we are reading a specific number of characters, as long as
+	  mb_cur_max > 1
+
+subst.c
+	- expand_word_internal: some improvements to code that converts istring
+	  into a WORD_LIST * to avoid multiple allocations and copies of
+	  istring, which is already malloc'ed memory -- reduce number of malloc
+	  and free calls

+expr.c

+
+builtins/evalstring.c
+	- should_suppress_fork: make sure to check for traps on EXIT and
+	  ERR, since any_signals_trapped() only checks for `real' signals,

+eval.c

+subst.c
+	- parameter_brace_{patsub,remove_pattern,transform,casemod}: save and

+	  error messages.  Fixes use-after-free error reported by
+	  op7ic \x00 <op7ica@gmail.com>
+	- string_extract_verbatim: make sure when we increment i by 2 due to
+	  a CTLESC or CTLESC-CTLNUL that we don't read past the end of the
+	  string. This can happen if the string ends with an odd number of
+	  CTLESC chars. Fixes oob-read error reported by
