Sigh.  You are right.

However, the said project is kind of exception.  The binaries are there 
from the very beginning - they are indivisible part of the project and it 
won't work without them.  This is why i am not worried if i revert to 
previous source code version, but actually check-out fresh binary - in my 
case it won't break things.

Damn, i knew you'd say something like this. :-)

Changes don't happen too often, but the size of everything binary in the 
tree easily goes to about 100MB.  Three commits later it ends up at about 
300MB...
