That's only true for the much easier injection case where you generate 
_both_ files together.

From an external git hash-attack standpoint, that's not a very useful 
case. It's much more useful if you can make a new file that has a hash 
that matches a given old file, and in that case, the filelengths are 
likely not the same.
