[PATCH] D60541: [clang-format] Use SpacesBeforeTrailingComments for "option" directive

[Donald Chai via Phabricator via cfe-commits]

AnnotatingParser::next() is needed to implicitly set TT_BlockComment
versus TT_LineComment.  On most other paths through
AnnotatingParser::parseLine(), all tokens are consumed to achieve that.
This change updates one place where this wasn't done.
