[PATCH 5/8] SubmittingPatches: improve extra tags advice

["Josh Soref via GitGitGadget" <gitgitgadget@gmail.com>]

From: Josh Soref <jsoref@gmail.com>

Current statistics show a strong preference to only capitalize the first
letter in a hyphenated tag, but that some guidance would be helpful:

git log |
  perl -ne 'next unless /^\s+(?:Signed-[oO]ff|Acked)-[bB]y:/;
    s/^\s+//;s/:.*/:/;print'|
  sort|uniq -c|sort -n
   2 Signed-off-By:
   4 Signed-Off-by:
  22 Acked-By:
  47 Signed-Off-By:
2202 Acked-by:
95315 Signed-off-by:

 You can also create your own tag or use one that's in common usage
 such as "Thanks-to:", "Based-on-patch-by:", or "Improved-by:".
 
+Extra tags should only capitalize the very first letter, i.e. favor
+"Signed-off-by" over "Signed-Off-By" and "Acked-by:" over "Acked-By".
