Hi Maxim,

regarding the revision field, I don't plan on doing too many nightlies, given
that I went two weeks without trying to invoke the renpy binary.  For the future
reviewer who has to read through all of this again when version 8 hits, I think
not indenting the package description makes more sense (particularly as I
anticipate possible changes in the phases due to renpy build weirdness).

The other suggestions should be applied (sans G-Expressions which are in the
next patch).

Cheers
