[PATCH v2 01/10] sequencer.c: remove broken support for rfc2822 continuation in footer

[Brandon Casey <drafnel@gmail.com>]

Commit c1e01b0c generalized the detection of the last paragraph
signed-off-by footer and used rfc2822 as a guideline.  Support for rfc2822
style continuation lines was also implemented, but not correctly, so it has
never detected a line beginning with space or tab as a continuation of the
previous line.

Since a commit message is not governed by the line length limits imposed
by rfc2822 for email messages, and it does not seem like this functionality
would produce "better" commit messages anyway, let's remove this broken
functionality.
