 `curl_msnprintf()`: literal text plus `%s`, a `size_t` and a `curl_off_t`,
 with no width or precision. Where `snprintf` measures an elaborate format,
 this measures the common one.

+This test has a list of 180+ different strings holding specific timestamps.
+They include both valid and invalid dates. The test parses each such timestamp
+100,000 times each. The result is the average time in nanoseconds the date
+parser function curl_getdate() took across all invocations.
