[elbe-devel] [PATCH v2 4/7] commands preprocess: isolate "pass_through" options

[Torben Hohn]

"elbe preprocess" will be called from "elbe initvm" and "elbe pbuilder"
in order to forward options these commands have to define them too.
Add a function, that adds the forwardable options to an option parser.
