Correct various minor diff copy behaviors

Summary:
Ref T12822. Fixes a few things:

  - Firefox selection of weird ranges with an inline between the start and end of the range now works correctly.
  - "Show More Context" rows now render, highlight, and select properly.
  - Prepares for nodes to have copy-text which is different from display-text.
  - Don't do anything too fancy in 1-up/unified mode. We don't copy line numbers after the `content: attr(data-n)` change, but that's as far as we go, because trying to do more than that is kind of weird and not terribly intuitive.

Test Plan:
  - Selected and copied weird ranges in Firefox.
  - Kept an eye on "Show More Context" rows across select and copy operations.
  - Generally poked around in Safari/Firefox/Chrome.
