log-tree.c: cleanup a bit append_signoff()
This patch clean up append_signoff() by moving specific code that looks up for "^[-A-Za-z]+: [^@]+@" pattern into a function. It also stops the primary search when the cursor oversteps 'buf + at' limit. This patch changes slightly append_signoff() behaviour too. If we detect any Signed-off-by pattern during the primary search, we needn't to do a pattern research after.
