I think this is useful, thanks for the patch.

This breaks the "check-git-log.sh -N" usage, since "-N" is not a valid
range for git-log-fixes.sh.
Generates warning:
.../scripts/git-log-fixes.sh: illegal option -- 6
usage: git-log-fixes.sh [-h] <git_range>

This is good for developer, but since "CC: xx" tags removed when patch
applied, this will generate warnings when run against existing history.

I don't know what can be done for this.

Or should we keep CC: tags in commit log perhaps?
