case statements should be defined using a colon.

As per the PSR-2 coding standard, case statements should not be wrapped in curly braces. There is no need for braces, since each case is terminated by the next break.

There is also the option to use a semicolon instead of a colon, this is discouraged because many programmers do not even know it works and the colon is universal between programming languages.

6675
	 * from Jetpack in favor of using a single file. In effect "imploding"
6676
	 * all the files into one file.
6677
	 *
6678
	 * Pros:
6679
	 * - Uses only ONE css asset connection instead of 15
6680
	 * - Saves a minimum of 56k
6681
	 * - Reduces server load
6682
	 * - Reduces time to first painted byte
6683
	 *
6684
	 * Cons:
6685
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6686
	 *		should not cause any issues with themes.
6687
	 * - Plugins/themes dequeuing styles no longer do anything. See
6688
	 *		jetpack_implode_frontend_css filter for a workaround
6689
	 *
6690
	 * For some situations developers may wish to disable css imploding and
6691
	 * instead operate in legacy mode where each file loads seperately and
6692
	 * can be edited individually or dequeued. This can be accomplished with
6693
	 * the following line:
6694
	 *
6695
