Ignore markdown hash/heading marks?

Shouldn't:

echo '### A small tool and library (crate) that capitalizes English text' | titlecase

produce:

### A Small Tool and Library (Crate) That Capitalizes English Text

instead of:

### a Small Tool and Library (Crate) That Capitalizes English Text

?

The implementations I based mine on don't do that so mine doesn't either. It does seem like it would be a reasonable addition for a common use case. Perhaps all leading punctuation should be skipped over?
