Subject: patman: Avoid blank lines between tags
X-Git-Tag: v2021.10~60^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5974718752d80d3772bd0ef45630ba4ea8c2eb64;p=platform%2Fkernel%2Fu-boot.git

patman: Avoid blank lines between tags

In some cases 'patman status' leaves a blank line between the sign-off
and the tags it collects from patchwork. Fix this and add a test.
