* This moves our "development" versions from .dev.js to .js (same for css). * The compressed version then moves from .js to .min.js (same for css). By switching to the standard .min convention, it sets expectations for developers, and works nicely with existing tools such as ack. fixes #21633. git-svn-id: http://core.svn.wordpress.org/trunk@21592 1a063a9b-81f0-0310-95a4-ce76da25c4cd

* jquery.suggest 1.1b - 2007-08-06
|
|
* Patched by Mark Jaquith with Alexander Dick's "multiple items" patch to allow for auto-suggesting of more than one tag before submitting
|
|
* See: http://www.vulgarisoip.com/2007/06/29/jquerysuggest-an-alternative-jquery-based-autocomplete-library/#comment-7228
|
|
*
|
|
* Uses code and techniques from following libraries:
|
|
* 1. http://www.dyve.net/jquery/?autocomplete
|
|
* 2. http://dev.jquery.com/browser/trunk/plugins/interface/iautocompleter.js
|
|
*
|
|
* All the new stuff written by Peter Vulgaris (www.vulgarisoip.com)
