I don't think this information is relevant to be placed in
the commit description. Perhaps it would better placed after
the scissors mark (the --- after the message) which is sent
to the mailing list but ignored in the final commit.

Btw, since we're in Git we can use Git's special powers to
do that. This is equivalent to your command line:

   $ git grep 'test -[efd]' -- 't/*.sh'

And this may be more useful, separating the output per file
and using pathspecs to filter the tests (files that begin with
"t") from other helper scripts inside t/:

   $ git grep --heading --break 'test -[efd]' -- 't/t*.sh'

I wrote a blog post about git-grep and other tools [1] that
may be useful for you.

The code itself looks good to me!
