This is still pretty subtle (using the added newline that is added after
a non-footer to turn the invalid footer into a valid one), but

 * it is clear from the code that it will work correctly
 * the new test ensures we'll continue to support this case
 * it is understandable after a little head scratching
 * I'm hoping the subtlety will go away once the code learns to deal
   with ordinary non-footer text that has a missing newline

nit: Should this use a more typical sign-off line with an email
address, to avoid a false-positive success in case git becomes more
strict about its signoffs in the future?

Something like

	printf "title\n\nSigned-off-by: S. I. Gner <signer@example.com>" >msg &&
	sha1=$(git commit-tree -p initial mesg-with-footer^{tree} <msg) &&
	...
