Re: [jgit-dev] autocrlf=input with CRLF in repository does not behave li

Sorry, for top-posting...

I've been using a CRLF'ed working tree on a Mac. Wish some Windows users could
test this too before release, or even before merge.

Anyway, a cherry pick failed because of this code in the ResolveMerger,

		// Worktree entry has to match ours to be considered clean
		boolean isDirty = work.isModeDifferent(modeO);
		if (!isDirty && nonTree(modeF))
			isDirty = !tw.idEqual(T_FILE, T_OURS);
		// Ignore existing empty directories

The working tree iterator declares the file clean, but then there is an additional comparing with the
id. Why is it not enough that the WTI says it's ok? The file is not included in the merge base.
