Missing `\n` at the end of `log!` and `log_chronik!` macro invocations in Rust files are now reported by LogLint.
Note this currently has known false-negatives: string literals spanning multiple lines in Rust are done like this:
```
let string = "long text that \
doesn't fit in one line";
```
The current regex doesn't catch this, as in C/C++ the equivalent would be:
```
char *string = "long text that "
"doesn't fit into one line";
```
This will need to be addressed.
