description:
lint: resolve conflict in grammar for __real__ and __imag__

There is no need for extra rules for '__real__(term)' since that is
already handled by the simpler '__real__ term', just a few lines further
up in the grammar.  Likewise for __imag__.

The GCC manual does not mention anything about parentheses either.
