It is a very good discipline to use size_t to index into an array
whose size is externally controled (e.g., we slurp what the end user
or the server on the other end of the connection gave us into a
piece of memory we allocate) to avoid integer overflows as "int" is
often narrower than "size_t". But this particular one is a Meh; the
keywords[] is a small hardcoded array whose size and contents are
totally under our control.
