Entity parsing

[Peter R. <php...@pe...>]

doesn't seem to work any more. Looking through the class, it looks like the 
problem is to do with the translateAmpersand function, though I tried 
disabling this function and that didn't fix the problem, so there must be 
more to it. The documentation for this seems to be saying that the parser 
should be prevented from, er, parsing, which seems odd to me - if you don't 
want entities parsed, why use them? - but if this is necessary, can it be 
made switchable please: yes I want entities parsed, or no I don't. I don't 
use entities extensively but they are a modestly useful function.
