As an alternative implementation, to avoid creating lots of intermediate
substrings, we could check if we're inside a hunk and, if so, perform a
regular expression replace to remove the diff indicators. If the region
covers text outside of a hunk, then we could copy the text normally, as
if the user pressed M-w.
