plumb start window webbrowser ''''$0''''

should work.  the problem is that it gets
tokenized twice -- once by plumber and
once again by rio (window can only pass a single
string to rio).

note that you have the same problem on the
command line.

	g% cat /bin/webbrowser
	#!/bin/rc

	# simplest webbrowser ever
	whatis '*'
	sleep 100
	g%
	g% x='=hello'
	g% window webbrowser $x	# fails
	g% window webbrowser ''''$x''''	# works

there should probably be quoting and unquoting
operators in the shell to make things like
this less troublesome.  (if window could
add the necessary quotes before handing
off to rio, we'd be better off.)  but it's not
clear what the syntax should be.  i kind of
which td had used $^ to concat like byron
did, and then we could use $" to produce
a quoted version of a list.  we'd still need a
way to unquote a string into a list though.
note that $' is out because

	g% '#a'=123
	g% echo $'#a'
	123
	g%
