+Disabling certificate revocation checks
+
+ Some SSL backends may do certificate revocation checks (CRL, OCSP, etc)
+ depending on the OS or build configuration. The --ssl-no-revoke option was
+ introduced in 7.44.0 to disable revocation checking but currently is only
+ supported for WinSSL (the native Windows SSL library), with an exception in
+ the case of Windows' Untrusted Publishers blacklist which it seems can't be
+ bypassed. This option may have broader support to accommodate other SSL
+ backends in the future.
