[Portland] xdg-su syntax

[Bastian, Waldo]

Hi,

It was suggested to me that it would be better for xdg-su to follow the
"sudo"-syntax rather than the "su -c" syntax because it has less
potential for getting the shell escaping wrong.
For illustration, to run "rpm -i '/tmp/some file'" as root the current
syntax is:
	xdg-su -c "rpm -i '/tmp/some file'"

The new proposed syntax would be:
	xdg-su rpm -i "/tmp/some file"

The drawback seems to be that if you want to do a shell command like
"cd /tmp; rpm -i 'some file'" you will still end up with
	xdg-su sh -c "cd /tmp; rpm -i 'some file'"

Opinions?
