description:
Don't attempt to unput(EOF).
According to lex(1) (the manual page for flex, which is what we use for lex):
        Finally, note that you cannot put back EOF to attempt to mark the
        input stream with an end-of-file.

Fixes PR bin/8707, which had been reclassified as a toolchain bug.
