include and excerpt-include macros do not render wiki markup if they are part of an excerpt

If you try to put an include or excerpt-include macro within an excerpt macro, the wiki markup in the inclusion will not render.

For example, create a page named '_myInclusion' with the following content:

This is text that needs to be rendered. *bold*, _underscore_, [a link|http:\\www.google.com].

Then create another page 'Example Page' that has '_myInclusion' within an excerpt macro, i.e.

{excerpt}

My inclusion goes here: {include:_myInclusion}

{excerpt}

When you save 'Example Page', all of the content included from '_myInclusion' will not be rendered. The wiki markup will be shown instead.
