People seem to add the above to their test-path helper patches, but
unless the coverage of the work is fairly thorough and you want to
say "all the similar issues should be found with this command and I
addressed all of them", I do not see much point saying how you found
one of them and addressed it.

You could have used "git grep -e <pattern> -- t/\*.sh", or you could
have been working to fix something in t9200 and noticed these while
you were doing something else to the file.

I do not see it as too huge a deal and it is probably not a cause to
send in another iteration once it is already written, though.

But the lack of sign-off is reason enough to require an update.  

For an "introduction to the project" patch, the change itself is not
as important or interesting than demonstrating that you studied
CodingGuidelines and SubmittingPatches well.
