--- Comment #13 from Jilles Tjoelker <jilles at FreeBSD.org> ---
This change breaks various ports. Some problems are in Mk/bsd.port.mk
(COPYTREE_BIN and COPYTREE_SHARE) affecting many ports and in lang/ruby*. These
are all of the form ${SH} -c 'command' -- arg0 arg1 ... where current sh will
expand $0 to arg0 and $1 to arg1, while POSIX says to and this patch makes sh
expand $0 to --, $1 to arg0 and $2 to arg1.

The fix is to remove the -- and to, if arg0 may start with '-', add a dummy
arg0 and adjust the command string accordingly.

These fixes need to be committed to ports before the sh patch can be committed.
