It seems that this was a copy-paste from a few of tests before this
new piece.  They all _expect_ to fail, so probably nobody bothered
to inspect the outcome ;-)

I just looked at what actually goes to COMMIT_EDITMSG with this test
that expects to succeed.

$ cat .git/COMMIT_EDITMSG
hello /home/gitster/w/git.git/t/trash directory.t7500-commit-template-squash-signoff/.git/COMMIT_EDITMSG

So, you're right to say "$@" will be given in addition to "hello" as
arguments to "echo".  That extra argument is to tell the editor the
path to the edited file.

We'd probably need a preliminary clean-up patch to fix all of these
in the vicinity.

Thanks.
