Could you please educate me, that which operations depend on "doing 
subtree comparisons based on the object name", and in about which 
files/functions those comparisons are done? Also, do you mean by "object 
name" the SHA1 of the object, the filename of a file/directory, or 
something else? I'd like to know, which parts of the code I should read, 
to get a better mental model on how Git works.
