Referenced-style links

[tomassliz]

When I try wrote something like this with some tabs after colon:
Link to page [Google][] and next text.
[Google]: http://google.com/

rendered link is broken, tabs are encoded to this result:
<a href="%09%09%09http://google.com/">Google</a>

On Daring Fireball is this description for referenced links style:

• Square brackets containing the link identifier (optionally indented from the left margin using up to three spaces);
• followed by a colon;
• followed by one or more spaces (or tabs);
• followed by the URL for the link;
• optionally followed by a title attribute for the link, enclosed in double or single quotes, or enclosed in parentheses.

I think, this is bug.

In fact, it's stated in the source code comments, but it's not implemented as you can see here

Nice work, thank you!
