It's fairly dep specific; that's effectivelly foo|bar when you think 
about it; it multiplies out to dep:foo? ( that block ) dep:bar? ( that 
block ) in a dumb PM (smarter one just leaves the tree collapsed and 
filters as it goes).

Phrased another way, I'm not sure we really need shorthand for the 
following:

x? ( blah )
y? ( blah )
z? ( blah )

into
x,y,z? ( blah )

It's a rare case; I could only foresee that potentially being of use 
for arch flags; ie, amd64,x86? ( blah ); which I'd write as 
"arch:amd64,x86? ( blah )" personally since I don't like the notion of 
introducing ',' into raw, non use group flags.

That said, I don't hugely care; people think it's useful, then have at 
it.
