The previous code would skip parsing with sub-parsers so these would not
work. Running full createTagsWithFallback1() in this case would cause
two problems:
1. We would have to propagate the extra callback arguments to
runParserInNarrowedInputStream()
2. And the callbacks after each pass should not actually be called in this
case because the caller expects these are called for the master parser,
not the sub-parsers.
So instead just do simple parsing without re-tries which are used only in
the C and Fortran parsers which lack sub-parser capability anyway.
