Make dashes and underscores treated the same when searching through tags.
Since people use both underscores and dashes to represent spaces, I think they should be treated the same in tags. Then people will not have to enter a multiple word tag twice.
The easiest way to do this would probably be just converting dashes into underscores when you enter in a tag.

I'm interested in some form of convention for spaces, dashes, and underscores. I tried to use a tag of two words, and it had three results: no space, a hyphen, and an underscore separating the words. Even if they point to the same content, it's confusing which I should use.
