Only in unstable, I presume...

These look quite nice!  Partial leapfrogging works much more solidly now
that we have the notion of unwritable caches.

Users might be interested that you can also have a writable global patch
cache living in
  ~/.darcs/cache
If I'm reading the code right, you just tack on a line to your
_darcs/prefs/sources:
  /home/bob/.darcs/cache
It makes darcs repositories a little less self-contained, but hey, if
you really want self-contained, don't use --partial.

Note:
  We've lost the ability to 'convert' an old fashioned inventory repo by
  just doing darcs get --hashed-inventory
  
  It now complains with "TODO: still need to implement copying of mixed
  inventories." I'm guessing that this is because we now do a
  copyInventory in copyFullRepository

  For now, we can get by with darcs init --hashed-inventory and pull but
  it would be nice to have that working :-)
  Would a darcs optimize --modernize-inventory be in order, perhaps?

do we still want that second copyInventory?
