Code cleanup, minor code enhancements to "misc.php"

[Latz]

I've added an amount of spaces to the code to make it WP coding standard compliant, changed " to ' where appropriate and added ";" at single line <?php ... ?> structures.

Please take a look at ​http://wpdevel.wordpress.com/2011/03/23/code-refactoring/

Also I don't think we are using spaces between square brackets.

In ​your post to wp-hackers you stated:

I was changing spacing for a function anyway because it was horrible to read and to understand

This is a good reason to refactor a particular piece of code. Refactoring the whole file, however, is not necessary. It should be avoided for the reasons pointed out in the WP Devel link above.

Which function were you originally refactoring to improve the readability of? IMO you should resubmit a patch with just the refactoring you originally intended.
