[PATCH] rawstr: Speed up Curl_raw_toupper by 40%
From: Lauri Kasanen <cand_at_gmx.com>
Date: Mon, 2 Nov 2015 17:09:45 +0200
Date: Mon, 2 Nov 2015 17:09:45 +0200
Rationale: when starting up a curl-using app, all cookies from the jar are
checked against each other. This was causing a two-second startup delay in
the Fifth browser.
All tests pass.
