+Subject: [PATCH 1/3] check_curl: Fix help for state regex option
+
+The help output of `check-curl` contained a typo,
+the real option is `state-regex` and not `regex-state` as
+the help suggests.
+Also added the two possible options to avoid confusion.

+Subject: [PATCH 2/3] check_curl: Parse state-regex option ignoring case
+
+Previously the --state-regex option accepted only "critical" and
+"warning" as values.
+This commit changes the strcmp there to strcasecmp to be more tolerant
+regarding the input.
