This patch adds WARNINGs for the subject line length and the format,
i.e., the sentence should start with a capital and end with a dot.
Signed-off-by: Eelco Chaudron <echau...@redhat.com>
---
v2: - Add test cases
- Made it work on files and git patches
- Changed it from 50 chars on the summary, to 70 chars on area
and summary. This way git log --oneline will fit on a 80 char
line.
