Thanks for the report; it looks like a bug indeed.  I had probably
overlooked that case (where there is no compression but we are still
dealing with an archive format).  The annoying thing is that touching
this code will trigger a world rebuild; so unless we find other big
problems and batch the fixes, it may not be worth it.

The site.py problem you reported may be one, if I find a solution.

Other things on my mind:

1. rustc bootstrap from 1.39 (the itch to make it faster comes back
everytime I have to build it ;-)).

2. fontconfig update that should allow per-profile fonts management via
  XDG_DATA_DIRS (I have the commit ready, but failed to test it due to
  having to build rust and getting distracted by 1. :-))

Not a very useful reply in itself, but I felt that communicating what
I've been busy with was better than a longer silence :-).

Thank you,

Maxim
