The 4 shift/reduce conflicts have to do with the associativity of the
logical operators, e.g.:
NOT expression AND expression
expression AND expression AND expression
etc. The shift/reduce conflicts _are_resolved (according to the output
from bison -v), so the conflicts seem to be benign.
Right now I marked the 4 shift/reduce conflicts as expected, but perhaps
someone more knowledgable about yacc grammars could take a look at it?
