I'm not sure what you mean by "whitespace disaster".  Your post looks
fine to me.

Are you sure it IS a job?  It might not be.

You can also look at the "owner-report.scm" which shows how to detect if
it's a payment or invoice.  You might need to go through the Lot, which
requires having access to the Split from the A/R and/or A/P account and
not necessarily the transaction itself.

Hmm... THAT might be a bit harder.
