patch: be more tolerant to diffstat failures (issue 865)

Sometimes, revisions cannot be represented by a regular diff, only a git diff
would capture binary files or permission changes. diffstat cannot handle git
patches and will output "0 files changed" when fed with an empty diff. We
cannot consider the latter to be an error, unless we rewrite diffstat to handle
these correctly.

#!/bin/sh

hg init

echo "Is there an error message when trying to diff non-existing files?"
hg diff not found

echo "Is there an error message when trying to add non-existing files?"
hg add not found
