Reserved values in Hashing.h

Hi,

The Doxygen comment for the hash_code class in ADT/Hashing.h states that two values are reserved:

"Also note that there are two numerical values which are reserved, and the implementation ensures will never be produced for real hash_codes. These can be used as sentinels within hashing data structures."

However, there doesn't seem to be any further comment on what values are reserved. So, are there actually any reserved values (which ones?) or is this maybe just a stray comment?

Thanks in advance for any hint!

The comment is outdated, support for the special reserved values was removed in r151865. It's not really useful to have sentinels for the hash value itself.

I'll remove the comment.
