Since vim-scala higlights when word without checking word boundary, it highlights a word like elsewhen partially.

This is a real code which I'm writing with Chisel3.

This PR fixes to check the word boundary. Now it does not highlight entire elsewhen method name correctly:

I also found other words had the same issue so I fixed them as well.
