Markdown patch for link id bug

In using Markdown I found one problem, one I'm surprised hasn't been reported before. (I looked through the Markdown mailing list archive briefly, but didn't see anything on this; perhaps people consider the current behavior a feature, not a bug?)

I make extensive (really, almost exclusive) use of reference-style links, and noticed problems when I word-wrapped my paragraphs, so that the resulting text looked something like the following:

    ... This is a word-wrapped line that contains a [Markdown
    link][] with null link id and link text split across two lines.
    Here's another [Markdown link using a non-null link id][second
    link] where the link id is split across two lines ...

    [Markdown link]: http://...
    [second link]: http://...

In both the above cases Markdown 1.0 doesn't recognize the presence of a link.

The fix is pretty simple (I think): Just convert newlines in the link id to spaces before checking to see if a given link id has been defined; see my Markdown 1.0 patch for the diffs from Markdown 1.0. Note that the bug is still present in the Markdown 1.0.1 release, so I've made a Markdown 1.0.1 patch available as well.
