Re: [PATCH v2 10/14] difftool: add various git-difftool tests

David Aguilar, 07.04.2009:

t7800-difftool.sh tests the various command-line flags,
git-config variables, and environment settings supported by
git-difftool.

The original broke the test suite on Mac OS.
Testing difftool.<path>.path is hard without internal support
for a fake tool.

Mac OS doesn't have the "echo" command?
