+	  whether or not we're trying to append a string to a string variable,
+	  and optimize that using realloc/strcpy.  Based on a log-ago

+sig.c
+	- set_signal_handler: set SA_RESTART for SIGWINCH, so window size

+execute_cmd.c
+	- coproc_pidchk: if MULTIPLE_COPROCS, call cpl_search to find coproc
+	  associated with pid, don't remove it from the list with cpl_delete.
+	  Just mark as dead and wait for coproc_reap/cpl_reap to take care
+	  of disposing it
+	- execute_coproc: NEW FEATURE: run the coproc name through word
+	  expansion before creating the coproc; this allows unique coprocs
+	  to be created in loops. Originally requested way back in 2012 by
+	  Erik Brandsberg <ebrandsberg@juniper.net>

+command.h
+	- subshell_com: now has a line number member: line

+copy_cmd.c

+
+execute_command.c
+	- execute_command_internal: when executing a user subshell (`(command)'),
+	  set the line number and line number for the ERR trap from the line
+	  number saved in the subshell command struct.  Fix from
+	  Eduardo A. Bustamante López <dualbus@gmail.com>
+	- execute_arith_command: set line number for ERR trap from line number
+	  saved in the arith command struct.  Fix from
+	  Eduardo A. Bustamante López <dualbus@gmail.com>

+variables.c
+	- find_variable_nameref: treat a circular variable reference as
+	  referring to a variable of that name in the global scope (for now),
+	  if one exists.  PROVISIONAL change: inspired by suggestion back in
