Don't gray out function declarations

[Nodd]

There is no timing for the function declaration, but it would be visually clearer to not gray it out, except for functions that did not run at all.
The problem is with multi-line declarations, we have to not gray-out the whole declaration.

Bad good idea: ungray every line until the first line with a timing, the problem is taht there could be a docstring or comemnts inbetween, which should stay grayed out.
