Feature request: Add word wrapping to gitk display

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,
