[wp-hackers] Fixing some SSL cases for 3.4

I'm all for this change as much as I am for the root-relative url switch because it improves performance and robustness of wp.
I'm even in support of putting wordpress-https AND my own root-relative-urls out of business if possible, but schemeless urls generated by the system would not put either to bed because of content urls and the long-standing assumptions made in hundreds of plugins, not just wordpress-https.
Here's the strategy I took to fix the SSL problems you pointed out:
In addition to the tickets you reference for open/existing ssl problems I discovered a number of undocumented ones while refactoring the core of wordpress to support root-relative urls. When I realized it could be achieved via a plugin, I backed out all of the work except for this scheme refactoring. I didn't keep all of the ssl fixes because after finding half a dozen or so I realized that I could spend another week finding more. This patch was just to get the ball rolling on a strategy for moving forward.
Implement this patch, and then wrap scheme(...) around each of the referenced code points in those trac tickets and I think you'll find the problem solved... temporarily. I say temporarily because it's only a matter of time before someone extends the core framework in some way related to urls and forgets to wrap scheme() around it, in the same way they forgot to do the is_ssl() check, or http/s string substitution in those existing tickets.
(and yeah I totally should have seen that 3.4 reference in the subject, or in the text, or every other place it was plastered! :D)

"last minute stake in the 3.3 game"
This work is targeting 3.4, so not to worry. The point is to put http://wordpress.org/extend/plugins/wordpress-https/ out of business, except for shared SSL certificate support. That seems like enough of an edge case that it can be delegated to a plugin.
