Hi,
I am referring to this,
http://www.gnu.org/software/diffutils/manual/html_node/diff-Performance.html

Normally diff discards the prefix and suffix that is common to both files
before it attempts to find a minimal set of differences. This makes diff run
faster, but occasionally it may produce non-minimal output. The
--horizon-lines=lines option prevents diff from discarding the last lines lines
of the prefix and the first lines lines of the suffix. This gives diff further
opportunities to find a minimal output.

Is there an example to support this conclusion that if the common prefix and
suffix are discarded first, the result is not minimal?
Thanks,
Albert
