No worries, easy enough to do if I'm already updating the others.
I would like to be able to run this tool on my system, though, to see if
anything else gets flagged after fixing the above mentioned issues. But
the tool fails for me as I described in another post. The reason I say
that is, for example, the issue about the comment description ending with
a period was actually in multiple spots of the commit, even though the
tool only flagged one. I'd hate to think I've fixed everything only to
have the tool find more issues after I've submitted another series, all
because I couldn't run the tool.
