1. Handle closing flow sequence after explicit key …

   Currently after an explicit flow key '?' in a flow sequence, an immediately
   following closing ] is ignored by the parser:
   
       % echo '[ ? ]' | ./tests/run-parser-test-suite --flow keep
       +STR
       +DOC
       +SEQ []
       +MAP {}
       =VAL :
       =VAL :
       -MAP
       Parse error: did not find expected ',' or ']'
       Line: 2 Column: 1
       % echo '[ ? ] ]' | ./tests/run-parser-test-suite --flow keep
       +STR
       +DOC
       +SEQ []
       +MAP {}
       =VAL :
       =VAL :
       -MAP
       -SEQ
       -DOC
       -STR
   
   It is read correctly by the scanner as a YAML_FLOW_SEQUENCE_END_TOKEN, and
   the flow_level is decreased. Then it is passed to the parser where it gets
   ignored.
   This leads to invalid YAML being accepted, and valid YAML resulting in an
   error.
   
   Also the flow_level is incorrectly decreased, so you can nest sequences
   like that without running in to the MAX_NESTING_LEVEL.
