Don't call rstrip on the result of Node.text()

The result of calling Node.text() should already have leading and
trailing whitespace stripped so there's no need to call rstrip() on it.
This will hopefully help zero in on where trailing whitespace is
creeping in from certain bits of Doxygen XML.

This leaves the following places where we explicit strip trailing
whitespace:

1. In `<computeroutput>` elements
2. In function definitions (where the `<type>` of a `<param>` might have
   trailing space)
3. In a macro definition (where the `<initializer>` might have trailing
   space)
