Code review comment for lp:~stolowski/unity-scopes-api/fix-1393382-rtm

Looks good, thanks!

Very minor fix:

error("could not open scope directory: " + scope_dir + "\n");

The trailing newline shouldn't be there. error() automatically appends a newline. (You need a newline only if you want to force an error message to include a line break explictly.)
