Well, the subject say everything... the docstring of cl-do/cl-do*
resembles one of my phone calls :-(
Considering their names (do), it might be useful talk a bit about
what the macros do :-)
There is also room to say something on their arguments.
We could add a link to the proper info manual node as well, as in
the `cl-loop' docstring.
