Investment anomalies?

[aga]

A few months ago I committed a fix to correct absence or mis-labelling 
of the Price field in investment transactions.  While doing some 
checking, I noticed that a Sell transaction still is incorrect and I 
shall be submitting a fix for this.

Also, I've noticed that a Reinvest Income transaction appears to require 
an income category to be specified, although the amount may be zero. 
This doesn't seem right to me, but before I 'fix it', I'd appreciate 
views from other users, who have an opinion on this, as I know some have 
their own particular use of some of the fields, which might not be what 
I would expect.  And, the user is always right...
