Our builtin_diff() wants to know whether break-detection found a complete rewrite, because it changes how the diff is shown. However, when calling out to an external diff, we don't pass this information along (and doing so would require designing a new interface to the user-provided program). Let's drop the unused parameter to make this fact more clear. Signed-off-by: Jeff King <peff@peff.net> --- An alternative is to pass $COMPLETE_REWRITE in the environment. That would avoid disrupting existing external diff callers, and they could peek at the information if they really cared. But given that nobody has actually asked for this, I'm inclined not to add a new interface element that we'd then have to support forever. diff.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
