Fixed the example, I realized it was wrong since I copied it and got an error:
```
$ difft --sort-path
error: unexpected argument '--sort-path' found
tip: a similar argument exists: '--sort-paths'
```
The option is documented in `difft --help` and implemented in `difftastic/src/options.rs`.
7d8175dccf/src/options.rs (L375)
It's used correctly in the jujutsu submodule at the end of this file.
Migrates from the deprecated toCommandLineShell to toCommandLineShellGNU.
This changes the output format to use GNU-style concatenated options
(--color=always) with shell escaping for git config values. Both formats
were verified to work correctly with difftastic.
