Fixed the missing newline at the end of this cpp file locally.
This is the only patch left in the series without an RB.
If there's no objections I plan on pushing this once I get an RB on this.
Someone mind having a look at it?

> V2: Address review feedback from Timothy, plus fixes
> - Use a large enough char array
> - Actually test the formatted appending
> - Test that clear function resets string length
>
> V3: Port to gtest
>
> V4: Fix test makefile
> Fix copyright header
> Fix missing extern C
> Use more appropriate name for C-file
> Add tests for append_char
