String comparison in Dictionary::Retrieve

Line 240 in 1959def

if (ep->key.Empty() || ep->key == key)

There is an || ep->key == key condition, but it's checked in an optimized way (only do string comparison when the hash is the same) later, and only for non-dummy keys. Also there's a similar comparison in the perturb loop.

Why was that comparison added there?
