miscellaneous documentation fixes

[jhpalmieri]

With Sage 4.3.rc0, I get a few doctest failures from sage/doc, at least one of which is related to #7406. The attached patch fixes them. It also reinstates some doctests which were disabled until #5338 was fixed.

Oh, and it also changes a .. math block to match the actual LaTeX output from Sage.

I'm marking this as a blocker since without it, there are doctest failures.

Doctesting Sage 4.3.rc0 on sage.math results in the following failures:

The patch trac_7747-doc.patch fixes both of these failures. All doctests now pass on sage.math.

This is a duplicate of #7659, but the patch here does a little more. Can we use this patch instead of that one?

I've merged the patch here instead of the one at #7659.

Could you please make sure that burcin also gets author credit for this (for his work on #7659)? Thanks.
