That's reasonable.  The syntax doesn't even change much:
  char *sed_longpots = \
	"xfruitbasket\0" \
	"ywalrus\0" \
	"zturquoise"

(Still unsure if the two string segments or the one string segment is easier 
to read.  Either way, it's the same string...)

The thing is, this is blocked on a rewrite of getopt_ulflags(), which isn't 
hard I just haven't got _time_...
