Thanks for your answer. I thought of this approach already, but that
would break platform independence as well (since i had to compile that
utility for each platform) or it would take ages (because starting a new
java vm for each image is simply slow...).

So this would be my last resort :)

But I think I have a solution (at least a hack that is dirty enough so
that I cannot think of any cases it does not handle): since there are
always at least two text lines before the first attribute packet
("pub:..." and "[GNUPG:] ATTRIBUTE ..."), I'd just write a "filter
stream" that looks at the first line ending. if it is exactly CRLF, do
CRLF->LF conversion, if it is LF or CR only, do nothing.
