Search RSS2 Bug with Special Characters

[bhoogterp]

The RSS2 feed link automatically generated by wp_head() breaks and gives a 404 page if you have certain special characters...

Consider the search "John 3:16" (quotes included).

The search query results in: /index.php?s="John%203:16"
The search RSS2 feed link: /index.php/search/"John+3%3A16"/feed/rss2/

The first one works fine, but the second, which is automatically generated by WordPress' head function fails. Shows up in Google Webmaster tools as "Not Found".

Probably should have done this first, but it's the quote characters surrounding the search query that breaks the rss feed.
