I think probability of sha1 collision is very low, so we can ignore it.

According to this page :
http://bitcache.org/faq/hash-collision-probabilities

If we have 50000 different files, probability of collision with 160 bit
hash would be something like 10^-39.

So I don't think adding original filename is needed.
