grog generates a commandline based on `groff', so it must be clear which
options are real.

groffer uses `grog' and generates the needed `groff' options.  Again the
knowledge of `groff' options are necessry.

That's what I've done so far.  But that takes extra calling time.  As the
`groff' options don't change after installation, it makes sense to make
them available once at compile time.
