The code that comares lines is based on
contrib/diff-highlight/diff-highlight, except that it works with
multiline changes too.  It also won't highlight lines that are
completely different because that would only make the output
unreadable. Combined diffs are not supported but a following commit
will change it.

I was thinking that if gitweb were to support "diff refinement
highlighting", it would either use one of *Diff* packages from CPAN,
or "git diff --word-diff" output.
 

I just started to wonder if we couldn't use output from Jeff's
diff-highlight for gitweb. We could tech diff-highlight to produce diffs
marked with -{} and +{} (this is the notation used by Jeff in one of his
recent patches) or something like this and then just convert that into
HTML markup. Changes in gitweb would be minimal, we would reduce
redundancy and could focus on improving matching algorithm in one place.
