`Expando` cleanup in `.html()` and `.clone()` is too greedy

[maranomynet]

There's a bug in the rinlinejQuery regexp that makes it a bit too "greedy":

jQuery('<p> jQuery12="0" </p>').html();  // returns: "  "

Proposed fix:

In manipulation.js, ​line 1 should be changed to something like:

var rinlinejQuery = /(<\w[^<]+) jQuery\d+="(?:\d+|null)"/g,
                     ^^^^^^^^^^

and the replacements in lines ​156 and ​176 to reinsert the first matching parenthesis:

.replace(rinlinejQuery, "$1")
                        ^^^^

Actually this whole rinlinejQuery business is a bit of an ugly hack. Would it perhaps be feasible to fix the expando value in a way similar to what Andrea Giammarchi suggests in ​this jquery-dev post?

This regexp was optimized as part of the 1.4.3 fixes.
