Only calculate lookahead tokens when needed - #28
...
Lookahead tokens are only need if either:
(1) There is more than one rule that could be reduced in a given parser
state, or
(2) There are shift actions for a state and at least one rule that could
be reduced in the same state (to warn about shift/reduce conflicts).

Always compute lookahead tokens for reduce rules
...
Even if they won't be needed for the generated parser, they'll be useful
to detect shift/reduce conflicts.

"follow set", however it was used in a non-closed manner.
