Re: [PATCH 0/1] difftool: --no-index is incompatible with --dir-diff

Hmph.  So there is no point in using the dir-diff mode when you have
say two extracts of pristine tarballs?

I guess that's true.

The difftool will launch an external "directory diff tool" on two
directories populated with the two "things" (be it "the contents
from a tree-ish", "the working tree files", "the contents in the
index") in the end, but you already have two directories to be
compared when you run "diff --no-index", so there is no point in
going through the "difftool" middleman.  You can just feed the two
directories you have directly to that external directory diff tool.
