#3 file completion in first line does not work

[Michael Biebl]

Atm, to create a new CMakeLists.txt file, I choose New->File and then name the file CMakeLists.txt.
An empty file is then opened in the CMake Editor.
If I now start typing add_<TAB> in the first line, I get no autocompletion.
I have to change to line two(or greater), to get a working autocompletion.
