Disable external git diff tools when patching #273

Closed bcc32 closed 2 years ago

bcc32 commented 2 years ago

The GIT_EXTERNAL_DIFF environment variable can be configured to use a custom diff tool for interactive diff commands, but it may not produce an output compatible with git apply, so --no-ext-diff should be used to ensure that the diff output is usable for this purpose.
