Re: [PATCH] Teach git log --check to return an appropriate error code

Is it clear?  "git log HEAD~20..HEAD -- path" where path never changes
within the range would be !HAS_CHANGES, wouldn't it?

Perhaps "git log --exit-code --raw A..B -- path" should give the same exit
status as '! test -z "$(git rev-list A..B -- path)"'?
