Title: Specify page-range-format in MHRA.

The Chicago format that I've used here doesn't exactly match the style guide, because they technically want 107â€“08 rather than 107â€“8. Still, it's the closest thing available, and it's better than nothing. (It's a lot easier to search for an en dash plus a single number than to abbreviate everything by hand.)
