Hmmm. I think that the mode test and added \crlf can go, but the
decrement has to be there, at least if my test with and without \crlf in
the example tests that properly, so:

\scratchcounter\iffirstargument#1\else3\fi\relax
\advance\scratchcounter\minusone
\dorecurse\scratchcounter{\strut\crlf}%

Of course, I did not run through more tests and do not know if anything
else depends on this that should be tested.
