git-am assumes that patch is in email form, and in email there is
single empty line separating email headers from email body. What makes
git-am mangle your commit message is the fact that email format allows
for header to span multiple lines: you have continuation lines to have
indented by whitespace. So git-am thinks that " - bar - baz" is
continuation of Summary: header.

Decidely. This empty line would always be stripped.
