When adding robust $.include and ajax functionality I needed to be able to delays execution of ready(fn) functions 1) while requested includes were still loading and 2) while new ajax content (and related includes) were still loading. This required extending ready() to add extra ready conditions, but 1.4.2 had some issues that prevented this from being possible.

I made minor fixes in 4 places that will have no impact on working code, but will allow this type of improvement in the future. Comments marked MYEDIT explain exactly what and why.
