Is /tmp/jan-1 perhaps suffering whitespace corruption (which would
have happened at your end, as I can take the tail of your response,
remove the reply quotation, and apply it successfully), even though
I don''t think we had problems of this kind in the past? I''ll
attach the
patch here, just in case.
