Style nit: In this codebase, the space is omitted after the
redirection operator (i.e. >actual).

Nit: Given that the name "actual" is typically used in conjunction
with an "expect" (or "expected") file, its use here is somewhat
unexpected. Other possible names which might be more meaningful
include "patches" and "output".
