That's kinda my fault -- the original version just returned a char *,
and I observed yesterday that it would be nice to have one that didn't
allocate. Hence, one like snprintf and one like asprintf.
One like getcwd(3) instead might be a better idea. Although given a
fixed buffer the snprintf model for dealing with overflow isn't a bad
