Fine.  Now, at present the conversions between these forms are trivial.  
So the audit required is of everywhere there is an assignment / copy / 
input / output between different forms to ensure that the appropriate 
conversions are applied instead of a straight copy as at present.  For 
example, all the places printing IDENTIFIER_POINTER (id) with %qs become 
no longer valid, as IDENTIFIER_POINTER is in the internal form and %qs 
simply prints a string; %E may print an identifier as such, converting to 
the output form, but everywhere using %qs or some other output notation 
other than %E on an identifier needs checking and fixing.
