More ddoc complaints

[Adam D. Ruppe]

I have a pull request up to remove the big misfeature
of embedded html in ddoc, and it is pending action,
from me, to answer some of Walter's concerns.

But, I was updating the documentation for some of my
code (using std.ddoc and my improveddoc post-processor
to make it prettier and remove Javascript), and
I hit pain.

It is extremely difficult to document a HTML library
when your HTML examples are mis-interpreted as
markup!


Also, ddoc should outdent the code examples:

The examples are indented in my source to line up
with the declarations, but this indentation doesn't
make sense in the output!
