Thanks for pointing me out to that option, but it doesn't suit my need ei=
ther :-)
I now avoid it, by using --detach-sign, and i reconstruct input and outpu=
t into
a pgp/mime message. Since the content of a pgp/mime signed message
can contain multipart mime, and thus a boundary (which could contain more=
5 dashes), which has to remain intact.

Only problem left is how i can know which hash is used when i
execute --detach-sign.=20
Using --status-fd does not show the hash either.

Only thing i can think of is this:
gpg -a --clearsign -o output input
(get the used hash from the Hash: header)
gpg -a --detach-sign -o output input
(use hash, input and output to construct a rfc 3156 signature)

Am i missing something obvious to make this easier?
