str, bench: three checks that guard nothing

Browse Source 
sinit sets s->n = 0 as its first statement and no failure path restores
it, so stail's sclear after a failed sinit could never change anything;
say so in sinit's comment instead, where the contract belongs.  bench
compared a uintmax_t against UINT64_MAX and a size_t against UINT64_MAX,
both constant on any host this builds for.
