While xtr is *primarily* a hack for sharing strings, it is also a hack
for making more room for data.  In particular, if you have some code
that looks like, e.g.,

	printf("%s %d\n", a, b);
	...
	printf("%d\n", c);

xstr compiles this to

	printf(&xstr[OFFSET], a, b);
	...
	printf(&xstr[OFFSET+3], c);

(where OFFSET is some constant).  Presto, one copy of % d \n \0 deleted!
