Thanks for keeping at it. This looks good, but I have one question:

Here we drop two final lines from the email output. But if I just use
vanilla git and try this, I get nothing:
$ git format-patch -1 --stdout |
sed -n -e "/^-- $/,\$p" | sed -e "1 d" | sed -e "\$d" | sed -e "\$d"
Removing the second dropped line works:
$ git format-patch -1 --stdout |
sed -n -e "/^-- $/,\$p" | sed -e "1 d" | sed -e "\$d"

I guess the signature code is adding its own newline, so that the
default signature (or "--signature=foo") works. But it adds it
unconditionally, which is probably not what we want for signatures read
from a file.
Do we maybe want something like this right before your patch?

Subject: format-patch: make newline after signature conditional
When we print an email signature, we print the divider "--
\n", then the signature string, then two newlines.
Traditionally the signature is a one-liner (and the default
is just the git version), so the extra newline makes sense.
But one could easily specify a longer, multi-line signature,
like:
git format-patch --signature='
this is my long signature
it has multiple lines
' ...
We should notice that it already has its own trailing
newline, and suppress one of ours.

In the example above, there's also a newline before the signature
starts. Should we suppress the first one, too?
Also, I'm not clear on the purpose of the extra trailing line in the
first place. Emails now end with (">" added to show blanks):

Is there are a reason for that final blank line?
