Suggestion: Use ng-bind-html in default template

[dmitry-dedukhin]

Often, busy message has three dots at the end, which are coded as … in html.
I suggest to change default template:
<div class="cg-busy-default-text">{{$message}}</div>
to
<div class="cg-busy-default-text" ng-bind-html="$message"></div>
So, one can write something like this:
<div cg-busy="{promise: somePromise, message: 'Loading&hellip;'}">
