Commit Message

diff: empty files are the same

* Test case: "touch empty && perl diff empty empty"
* Program seems to hang; ctrl-c in perl debugger hints that we are stuck in Algorithm::Diff::traverse_sequences()
* Program grew to use >2GB of memory before I killed it
* traverse_sequences() doesn't seem to handle when both lists of input lines are empty (I didn't bother investigating why)
* Put a sanity check before diff()+traverse_sequences() are called; input files are read in total before diff() so the size of line list is know
* I also tested a non-empty file against an empty one
