Flawed handling of some characters in %postname% and %pagename%

[solarissmoke]

Say I write a post whose url is
http://example.com/wp/2011/01/hello-world/

All of the following requests cause wordpress to generate a 200 response and display the "Hello World" post:

http://example.com/wp/2011/01/-hello-world/
http://example.com/wp/2011/01/-hello-world--/
http://example.com/wp/2011/01/.-hello-world.--/

Same for pages. Basically, hyphens and dots (and possibly other characters) before/after the actual slug are just ignored.

Wordpress should either be 404'ing or redirecting such requests to the posts actual URL.
