[Geany-Devel] Colour scheme woes

[Lex Trotman]

On vim and rust, if the example below (from the Rust manual) does not
colour "Color" and "Point" as functions in the "let" lines then it
must also be parsing declarations, not using syntax.

```
#![allow(unused_variables)]
fn main() {
struct Color(i32, i32, i32);
struct Point(i32, i32, i32);

let black = Color(0, 0, 0);
let origin = Point(0, 0, 0);
}

```

Cheers
