ftplugin/yang.vim: Always add - to iskeyword

[cdleonard]

This makes it easy to navigate yang files using # and *

Seems reasonable to me. @dimbleby put this code in, though. Maybe he can offer a review/explanation?

I think the history is this commit where I used syntax iskeyword and then learned that old versions of Vim didn't support it. So my intention was to fall back to plain iskeyword in that case.

The only downside I can see to this change is that this setting will also apply to text in comments and strings, which isn't necessarily what you want, and much of the YANG that I see is mostly text description. But most of the words in those descriptions are unhyphenated!

In short: seems fine to me.

Sounds good to me, then!
