cmd: Handle special case tokens=* in for /f.
for /f allows a special syntax of tokens=* (rather than tokens=1* for example) which just means put the whole line into the next variable). Note the handling of the 'next variable' was wrong in the case of it being 'A' or 'a' as the wrap calculation was wrong, but this only affected using this new syntax.
