I was trying to match what other ob-*s do.  If the table assignment idea
was to be implemented (for instance), using a separate function may be
cleaner.  But the function is indeed currently not needed, so I removed
it.

I have added more complete docstrings, please let me know if changes are
required.

Tentatively done.

I use this function in the test as well to compare the full text output
so it is convenient to have a separate function.  Alternatively I guess
I could directly test the call to `org-babel-expand-body:generic' but
that seems less interesting as a test (should I remove the test
altogether then?).

The attached patch removes the useless definition of
`org-babel-plantuml-var-to-plantuml' (the regexp is moved to the
`org-babel-variable-assignments:plantuml' function) but keeps the
`org-babel-plantuml-make-body' function, useful for testing.  If you
would like me to remove the `org-babel-plantuml-make-body' function as
well, I will do that (how would you like the test to look like in this
case?)

Thanks for the guidance.
