	* lib/command.h: Document behavior of argv_concat function.
	* lib/command.c: (argv_concat) Calculate total string length first so
	  we can call malloc just once (instead of realloc'ing to add each
	  string element).
	  (do_echo,config_logmsg) Allow for possible NULL return value from
	  argv_concat.
