# Checks what the configuration parser reports on stderr. A key it does not
# know, a repo key before any repository and a filter set by a scanned
# repository without trust-scan-filters are each ignored with a warning naming
# the key, a repo filter in the main cgitrc passes without one, and a config
# cgit fully understands stays silent.
