Comment (by sirzooro):

 When `header()` function is used in tested code, PHPUnit will report error
 in tests because of "Cannot modify header information - headers already
 sent" warning. Therefore `header()` function in tested code has to be
 either prefixed with `@` or stubbed. My patch allows to use the latter
 approach.

 Regarding pluggable functions - I can use another approach, e.g. call
 `wp_header` action from `wp_header()` function, and hook a function to it.
