Use a case-sensitive version of SafeConfigParser everywhere This change has the potential to break existing setups, but the current behaviour (the keys in configuration files are always lower-cased) can bite us in a few places: - no way to use a Command in [defaults] - hgext.Extension doesn't work in [extensions] - you can't use an Upper/case/PATH in the [paths] section of hgweb.config - you can't (easily) protect paths with upper-case letters with the acl extension - you can't specify a /Path/TO/a/rEPO in the [reposubs] section for the notify extension
