Wilfred Hughes 0e3c57c64a Skip unique items before computing Myer's diff on text 
This substantially improves performance on text files where there are
few lines in common.

For example, 10,000 line files with no lines in common is more than 10x
faster (8.5 seconds to 0.49 seconds on my machine), and
sample_files/huge_cpp_before.cpp is nearly 2% faster.

Fixes the case mentioned by @quackenbush in #236.

This is inspired by the heuristics discussions at
https://github.com/mitsuhiko/similar/issues/15
