thanks.  I hoped for some less global setting.
Therefore I will cope with this question rather than
disable it.

Yes, now I see, you are right.  With the "&" a buffer
for the result pops up, which I don't want.  The "#"
prohibits that, but for the price of Emacs being
stuck. [At some stage of my experiments I got a "#
wrong reader syntax" messages, which hints to, that the
"#" was somehow interpreted by the lisp interpreter.]

I finally used an "elisp:" link and "start-process":

[[elisp:(start-process "ssh" "*ssh*" "ssh" "-N" "-L xxxx:192.168.xxx.xxx:xxxx" "-p xxxx" root@xx.xxx.xx.xxx")][xxx remote]]

This works as expected.

Thanks for your help.
