Alex Neundorf d62c51ddc2 -fix documentation from a module which has *only* documentation 
This is #10466. It didn't crash for me, but also didn't work.
The issue was that a line ending with something else than a # was considered as the
end of the documentation block. If there was simply the end of the file we didn't
get into the correct branch.
