OK, you all likely realize that I responded before I had got the three
more messages telling me what to do.

I'm sure it will work (three people telling you the exact same thing is
pretty convincing ;-) ), but what I don't understand is why/how, if I
want to

sudo echo 'media-video/xine-ui ~x86' >>/etc/portage/package.keywords

changing that to

"sudo echo media-video/xine-ui ~x86 >>/etc/portage/package.keywords"

is going to write the line

media-video/xine-ui ~x86

to /etc/portage/package.keywords-- i.e., why are the internal quotes no
longer necessary?

Or should it be

"sudo echo 'media-video/xine-ui ~x86' >>/etc/portage/package.keywords"

or will that *really* screw everything up?

(As you see, my understanding of bash is trying to improve, with only
very limited success :-) ).
