They're now available inside the TextWrangler application bundle at /Applications/TextWrangler.app/Contents/Helpers/edit.

Curious.  As I noted above, once I grabbed the command-line installer for TextWrangler, then /usr/local/bin/edit worked fine to start TextWrangler.  As far as I can tell, the web page should be corrected to say that the location is /usr/local/bin/edit as I noted above.
