Missing assumptions in 2 lemmas and 1 proposition
This I should have caught much earlier myself since the third part of
the statement of the lemma somehow really doesn't make sense without the
assumption that \mathcal{P} is closed under direct sums...! Moreover,
the condition that \mathcal{P} contains 0 is necessary for the
application of lemma 05T7... Argh!
Thanks to awllower

Construction of unbounded left derived functors
Right exact functors which commutes with colimits often have
left derived functors. It seems appropriate to discuss this in
the chapter on derived categories.
