Part of this confusion may be due to the fact that there is no such character as "dash" in ASCII. '-' is a minus sign or hyphen. (http://www.bbsinc.com/iso8859.html; http://www.w3.org/MarkUp/html3/latin1.html) English punctuation has at least three characters that look more or less like that. Editors argue back and forth over whether the en dash and the em dash are both needed, but at least the em dash -- or just dash, for short -- is logically very different from the hyphen.
Hyphens link words, as in "state-of-the-art interface", or parts of words, as in could cause a con- stitutional crisis
Dashes separate parts of sentences, as in the end of the paragraph before last.
Rendering a dash in ASCII, descended from doing so on a typewriter, is best done with two hyphens, preferably with a space after and possibly before as well. If somebody saw "-- " and described it as "dash-space", and someone else implemented that description as "- ", we'd wind up with what we have.
