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.

Thanks for reporting. Can you please send steps to produce a simple 
scenario where the diff from two algorithms is different so I can test 
why git-gui is not respecting the config. Make them as minimal as 
possible.

Also, +Cc Paul, the gitk maintainer.

I see this diff with both the default and patience algorithms on the command line tool.

I ran:
  $ git diff --diff-algorithm=default
and
  $ git diff --diff-algorithm=patience

Both yield the above diff. In fact, all 4 of "default", "patience", "minimal", and "histogram" yield the above diff. Which version of Git are you running? I am on v2.25.2.

PS: Please don't top post on the mailing list.
