I've added tests to bytecomp-tests.el as suggested. (why not
cl-macs-tests.el instead?)

I felt this word was not really important because (1) this is generated
code and (2) the docstring starts with "compiler-macro". Removing it
reduces the likelihood of the error message. I added an explanation in
the commit message. If the word is important I can add it back.

I tried to do that, is that what you want? I feel the added complexity
isn't worth it so I'm fine changing it back to the simpler version if
you change your mind.
