[racket-dev] request for code review on fix for pr 13471

I've run the tests that use the lexer, and it appears to pass.  But
since it's parser-tools/lex, I'd like a second opinion on this, just
in case I'm doing something very silly.

I've put this in my branch 'pr13471':

    https://github.com/dyoo/racket/tree/pr13471

After someone takes a look and says ok, I can push the fix upstream.
