As pointed out earlier, we want to see this line look like

    From: Rodrigo Michelassi <rodmichelassi@gmail.com>

This often comes from your commit object; you'd have to fix it there
to match "Rodrigo Michelassi <rodmichelassi@gmail.com>" used to sign
off this patch, something like:

 $ git commit --no-edit --amend \
   --author="Rodrigo Michelassi <rodmichelassi@gmail.com>"

while you have that commit checked out, and then

 $ git format-patch >patch.txt --stdout -v4 -1 HEAD

to prepare the patch, proofread it and then optionally after fixing
anything you found problematic in your proofreading, run git-send-email
on it.

Because your MUA already gives the name you use on your
signed-off-by line on the From: line, optionally you can just edit
the line out before sending, i.e. after the format-patch produces
the text file, before send-email sends the file out.

> Sorry for the wrong commit message on V2.

Anything you write in the body of the message, before the three-dash
line, goes to the resulting commit log message.  You do not want to
etch the above message into stone.  You can write such an ephemeral
message after the three-dash lines.  See these for examples.

"modern path checking methods" -> "test helpers used"

Also, "when detect" -> "when they detect", probably.

Ditto.

The changes to the test look good to me.

Thanks.
