The parse state is always updated after any buffer modification that
happened in the part before the position for which the state shall be
calculated.  The problem is, that syntax properties may override the
parse state.  And combined delimiters are always a pain (IIRC there were
discussions here whether in the middle of the C comment delimiters "/*"
and "*/" we are already or still in the corresponding comment.
