pqm error formatting

[Robert Collins]

PQM is currently giving strange error emails because of an old
internal code issue that mingles stdout and stderr without rhyme or
reason, and can mix them up mid-line.

Aaron contributed a partial patch for email attachment support, and I
have a polished version of that that should make things better, but
we've hit a few differences between lucid & the PQM machine itself
trying to deploy it; probably early next week should see it in place.

Bring on tarmac, I say.
