// We need to:
// - normalize indices; the ones we get from `diff` are 1-indexed.
// - account for how `diff` represents empty hunks -- essentially, it
// attributes the change to the *previous line* (which may be 0!). This
// differs from Python's difflib.
//
// http://www.gnu.org/software/diffutils/manual/html_node/Detailed-Unified.html:
// If a hunk contains just one line, only its start line number
// appears. Otherwise its line numbers look like 'start,count'. An
// empty hunk is considered to start at the line that follows the
// hunk.
//
// If a hunk and its context contain two or more lines, its line
// numbers look like 'start,count'. Otherwise only its end line
// number appears. An empty hunk is considered to end at the line
// that precedes the hunk.
