Manpages: clarify that the tunnel command is run following Perl's `exec` semantics.
It is passed to `/bin/sh -c` when it contains shell metacharacters; and
split into words and passed to execvp(3) otherwise.

(Since c8fb54897f046a5a3fb4c1d45dc21fd8bcd882e3 the value no longer
needs to stard with a forward slash.)
