Michael Shigorin a52b7476a4 initial "+shortcut" support and refactoring
It looks like the intermediate targets aren't all equal:
some define a finished feature while some create a common
lower level piece of configuration.

Let's do shortcuts for the former so that a distro line can be
more terse and descriptive; help targets in features.in/ tweaked
accordingly.
