Hi

For this diff

This seems to me a bug or should I apply some extra options to get expected behaviour?

PS$ git --version
git version 2.8.1

First of all, I ask you to realize that this diff makes it really, really
tedious to see your problem (too much going on there that is completely
unrelated to the bug: long lines, unnecessarily complex HTML code, too big
of a diff to compare two versions of the diff).

It takes but a little time to clean it up, and then it is so much easier
to make a case.

As to:

> +</div>                         <<<<<<<<<<<<<<<<<<<<<<<< IS NOT EXPECTED
>  <div id="colTools" class="eColTools"></div>

vs:

You asked for -w *and* for -b, i.e. ignore all white space *and* ignore
white space change. The combination is bogus, of course, as "ignore all
white space" includes "ignore white space change".

If you use only -b, you will see the expected change.

If you use -w, what you saw is actually expected, as git-diff was asked
not to see a difference between the indented vs the unindented </div>: it
really *ignores* all white space in that case. It is not like: ignore all
white space except when there are ambiguous matches.

Ciao,
Johannes
