  [flang] Fix parsing of WRITE(I+J) with more accurate look-ahead

The parsing of I/O units uses look-ahead to discriminate between
keywords, variables and expressions as part of distinguishing internal
from external I/O.  The look-ahead was inaccurate for variables that
appear as the initial parts of expressions.
