While it is easy enough to obtain this info from %debug, putting it
in the error messages is helpful when those messages come from user
reports (e.g. emails).

I am guessing that this change does not call for a new test or a
documentation update, but I'm happy to add one if asked.

Thanks @danielballan. Nicer error messages are always welcome! I've made one small suggestion.

Also I see that this is your first xarray PR. Welcome! We hope to see you contribute often.

Thanks! I agree that your proposed wording is better and I have committed it.

Thanks for the friendly welcome. I learned OSS as a minor pandas contributor back in my grad schools days, now glad to finally have a contribution in xarray. I love this project!
