[gitk PATCH 3/3] gitk: allow text-conversion in diffs

The "textconv" feature of git requires explicit enabling in
plumbing because the resulting diffs are not useful for
feeding to "git-apply" or "patch". Thus any callers should
make a conscious choice that they want the human-friendly
version.

Since the diffs presented by gitk are meant primarily for
human consumption, and not applying, it makes sense to allow
text conversion.

Paul,

I am cc'ing you only on 3/3 since it is the only gitk patch (the others
implement --textconv in git itself). Textconv is basically a feature to
show human-readable text diffs of binary files by doing a one-way binary
to text conversion (and so they can't be applied).

I think gitk would always want to support these; if not, then the
alternative is a "diff flags" option for gitk where the user could
specify this flag manually.
