til_settings: fix empty values in til_settings_new()
Previously if you supplied an empty setting value like so: "--module=compose,layers=" The interactive setup would get itself into an infinite loop because the layers setting is already present, but has a NULL value. This wasn't a NULL value, it was a "" value. The parser should just fallthrough to the value state from the equal state after recording the value's start pointer. This will result in a "" value getting allocated and assigned to the value before the loop breaks out on the '\0' immediately following the '='. There are probably other edge cases which need better handling here.
