I will change it to make sure that it states that you may want to port
your doctests if all you have is one massive set, but I do not think
it is "*way* too strong". Massive doctest inputs are bad enough as it
is to edit when you don't have a shift in syntax (e.g., I have a patch
waiting for 3.3 which causes entire test suites to skip because they
are a massive doctest and it is not reasonable nor easy to make
something conditional based on whether a trace function is set).
Trying to port them to new syntax is just that much harder (and a
complaint I came across online while researching the HOWTO).
