[PATCH] doc: point to diff attribute in patch format docs

["Peter Oliver via GitGitGadget" <gitgitgadget@gmail.com>]

From: Peter Oliver <git@mavit.org.uk>

From the documentation for generating patch text with diff-related
commands, refer to the documentation for the diff attribute.

This attribute influences the way that patches are generated, but this
was previously not mentioned in e.g., the git-diff manpage.
