The documentation says that the second parameter to preRenderingHandler is a reference to a hash that maps the placeholders to the removed blocks. And later it states that
Placeholders are text strings constructed using the tag name and a 
sequence number e.g. 'pre1', "verbatim6", "head1" etc. Placeholders are 
inserted into the text inside <!--!marker!--> characters so the 
text will contain <!--!pre1!--> for placeholder pre1.

A subsequent example uses verbatim, so clearly the user should assume that this parameter holds placeholders for verbatim, etc.

However, it turns out that such is not the case. The parameter only holds the map for pre.

The consequence of this is that it is *impossible to restore verbatim text that is manipulated in a plugin, once the endRenderingHandler (deprecated) is removed.

Further, the code is inconsistent with the documentation.

My suspicion is that some overzelous optimization was used to split the placeholders into separate maps, but forgot to pass all these maps into the preRenderingHandler.
