Feature request: Add word wrapping to gitk display

[Ailin Nemui <ailin.nemui@gmail.com>]

Hi,

when working on text files with long lines, "word diff" can produce
appropriate diff display. However, the long lines cannot be viewed very
well in gitk (requires excessive scrolling).

I found out that it is quite easy to achieve this

however I'm not otherwise knowledgeable about Tk to make this a
properly configurable switch. I think it would be a very nice addition
to have, a check box next to "Line diff/ color words" that says "Wrap
words in display".


Thanks,
