When a path is examined in the patch subcommand, any mode changes in the file are given to use in the diff header by git-diff. If no hunks are staged, then we throw out that header. But if _any_ hunks are staged, we use the header, and the mode is changed.
Since the 'p'atch command should just be dealing with hunks that are shown to the user, it makes sense to just ignore mode changes entirely. We do squirrel away the mode, though, since a future patch will allow users to select the mode update.
Signed-off-by: Jeff King <peff@peff.net> --- Like I said, I don't necessarily like this behavior, but it is a stepping stone to 1/2.
