Tilde in http link is not handled correctly

The following link (copy/pasted from an address line in FireFox)

http://dev.eclipse.org/viewcvs/index.cgi/~checkout~/platform-update-home/dev.html?rev=HEAD&content-type=text/html

Doesn't work-- The presentation is corrupted and clicking on the link doesn't go to the correct location.

The tilde's are the problem and a workaround is to use %7e instead of ~.

http://dev.eclipse.org/viewcvs/index.cgi/%7echeckout%7e/platform-update-home/dev.html?rev=HEAD&content-type=text/html

Seems like once I'm in a link "[http: ..." then ~ should not be treated specially until the link is closed with "]"
