Allows the expires header to accept a binary

Allows the expires header to accept a binary
I agree that it is a whitespace change, but I believe my whitespace change is correct. My whitespace change looks like this:
<pre>
tab tab tab ExpiresBin = cowboy_clock:rfc1123(Expires),
tab tab tab tab Req3 = cowboy_req:set_resp_header(
tab tab tab tab         &lt;&lt;"expires"&gt;&gt;, ExpiresBin, Req2),
tab tab tab tab {Req3, State2}
</pre>

Do you mind taking a look at it?
