It's always a judgment call, as to whether to use something like ``CALL`
or just plain CALL. Here, I'd like to opine that that the benefits of
``CALL`` are very small, whereas plain text in cet.rst has been made
significantly worse. So the result is, "this is not worth it".

The same is true of pretty much all of the other literalizing changes
below, IMHO.

Just so you have some additional input on this. I tend to spend time
fussing a lot (too much, yes) over readability issues, so this jumps
right out at me. :)
