styled-components support breaks highlighting

[ooflorent]

When using SC without tagged template string, the syntax coloring is broken.

I have fixed this in my local grammar but I don't think the above syntax is sound. I believe it should be terminated with an empty template string. I'm not using styled-components but I did a quick experiment and seemed to get strange results without a null string. Also see styled-components/styled-components#1124 (comment)

Many thanks. While the pattern is not commonly used, it is documented and used in libraries.

Still don't think it's correct just because it is equivalent. The example in the library is OK because of line 64, so the function chain isn't broken. Anyway, it should work for you now.
