Description

Came across this error today which detected uppercase letters in a buffer that is normalized to lowercase.

Would be nice to have this on the to_lowercase/to_uppercase transformations too

        "[ERRCODE: SC_WARN_POOR_RULE(276)] - rule 2003612: A pattern with uppercase chars detected for http_host.  Since the hostname buffer we match against is lowercase only, please specify a lowercase pattern.\n\n
