 The Visual Editor (TinyMCE) preserves multiple sequential spaces by
 turning the second (and following) spaces into some sort of funky
 invisible hard-space character.  Unfortunately, this character is NOT
 matched by ' ' (space) or '\s' (whitespace) in PCRE (preg_*() functions).

 Example:

 Put the following into the HTML editor on a post with uploaded images.

 {{{
 [gallery                 orderby=             "RAND()"]
 }}}

 Save the post, then preview.  Multiple refreshes should shuffle the images
 around randomly, because you're ordering by RAND().

 Now switch to the visual editor, and insert the same thing, with all the
 superfluous spaces, and save.  Preview the post -- you won't get random
 images, because the funky TinyMCE pseudo-space characters prevent the
 regex from parsing the attributes of your shortcode.

 Proposed solution: turn off TinyMCE's whitespace preservation code when
 within square brackets.
