[erlang-bugs] Incorrect specs documentation for common_test

[Loïc Hoguin]

There are a few functions and a few things in the documentation that say 
they return void() instead of ok or other things. For example the 
ct:comment/{1,2} functions.

I notice that ct doesn't use typespecs so that might be why it didn't 
get noticed until now. If someone has nothing to do, have at it. :-)
