Err, I'm sorry, but I don't quite get the point of the account summary 
covering a period of time. Okay, there is no commonly agreed sense of 
the term "account summary", at least not in the sense as there is for 
"balance sheet" and "profit and loss report". Until now I implied that 
the account summary would be used in the sense of a balance sheet. If 
that is the case, then a from-date should *not* exist since a balance 
sheet covers everything from minus infinity up to one specific date. 
Maybe in some settings this is different, but in the other cases it 
would be necessary to offer the possibility to switch off the from-date 
in that report.

Could you elaborate on what you are using the account summary for? My 
guess would be that you are actually using it as a kind of 
profit-and-loss report.

Thanks for your contribution, nevertheless. For the time being this 
report patch is a little too drastic to commit it into CVS as-is, but we 
might find a good use for this after some more discussion.
