That's much better than what I had suggested - and it would work for
your case with multiple trees in a sane manner as well.

The argument by Stefan Richter that '+' is already used informally as
"or later" is somewhat valid - maybe we could use an ampersand (which
originally stood for 'et cetera' - and other things). 

But then I don't know if that would confuse tons of scripts as the & has
lots of other meanings in various scripting languages.
