What we write in this neck of the woods is
	foo = ecpyalloc(s);
	foo = ecatalloc(foo, t);
where "ecpyalloc" sets foo pointing to an allocated copy of s
(a la "AllocCpy" in the 2.11.14 news software)
and "ecatalloc" sets foo pointing to a reallocation of foo with t catenated.
This avoids the need for a hardcoded constant entirely;
since you don't use one, you can't get its value wrong.
