#249 code completion for members is wrong

[Oliver Stöneberg]

The code completion doesn't care about the object being
a "real" object or a pointer. So you get the same
results on "." and "->".
If you got a pointer you should not get any code
complettion reuslts on "." and if you got the "real"
object you should not get any on "->".

I mentioned this problem in the comments of another bug
report I submitted before.
