That's not the part that needs clarifying. I think that fact that the 
string form drops final zeros is clear from lines 2-4.

The part that needs clarifying is how to choose the version number for 
the alpha releases leading up to version {X+1}.0. (Really, how to choose 
alpha version numbers in general, since I've had similar problems in the 
past.) From this statement, "X.Y (Z=0, W=0) is an alpha version for 
{X+1}.0" (Y>=90 already stated), I would expect that 5.91 would be a 
fine alpha version number for 6.0. Is it? If not, what should the alpha 
version number be?
