semicolons (or some sort of punctuation) seem broken about drawshield HOT 2 CLOSED

Thanks, I'm sure you are right, I will look into it - heraldic punctuation is 
generally not very consistent but in this case the intention is pretty clear.

Fixed and regression tested, will be in release 2.2a3.
There were two related errors, the semi-colon was not being looked for at the 
end of "semy de something" and was not being take into account if it occurred 
*before" overall. The example given is now drawn correctly, and if the final 
semi-colon is removed then the "overall" is placed over the third quarter only, 
which (whether it is heraldically correct or not!) is how I want to behave.
