Allow tags to start with non-letters

My use case: I don’t need to create a page for books in the Bible, but I would like to do tags to see where I reference various books for notes, sermons, daily journal, etc…

So for example #1Corinthians right now does not get treated like a tag but just renders as “#1Corinthians” w/o any hyperlinking or anything.

It would be cool if these tags acted the same as if I did #FirstCorinthians.
