Bug Report

gitk and git-gui are both not respecting git config.

When I set the diff.algorithm global config to patience, the command
line git respects the config. However, both gitk and git-gui don't.
When I use "git status -vv" to get a diff of the working directory,
the diff produced respects the algorithm choice. The diff of the
working directory in gitk and git-gui both still use the default diff
algorithm, rather than the algorithm from the config.
