… but since I liked the bonus of having the hval stored so much, merge
...
it with the array index; var.c says that
│ 1244 /* The table entry is always [0] */
so that we can have a special flag and a union which stores hval for
the table index, the array index otherwise (coïncidentally *hint hint*
they have the same size)

for now, until we really use kt*() otherwise, ifdef out tablep/hval

much better solution: save tablep and hash value¹ in the struct tbl entry

ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries
are still counted)

• make the hash functions print their result again

• optimise the one-at-a-time code for shell
