$* is for when you want to smash things together, whitespace-separated;

Can we be explicit and say "$@" in the commit message rather than bare
$@ since the unquoted form is not magical and acts exactly like $*.

Also: s/in to/into/

Nit: I have some trouble following what the commit message is actually
trying to say with "smash things" and "separate strings". It might be
simpler to say merely that use of "$@" in these particular instances
is overkill and possibly misleading to readers not familiar with the
finer details of $* vs. "$@".

The patch itself makes sense.
