Once this line is added to a package spec, it is likely to never show up
again, and its initial appearance may have a significant impact on the
build, so it is good to keep to not lose context.

The for-review.txt files were being generated with `git show` and thus
not compatible with `git send-email`. Use `git format-patch` instead to
fix this issue.
Also add a more prominent notice about the existence of for-review.txt
and its intended purpose.
