[Adrian Vasiliu]

Wherever possible, replace usages, for config flags, of array syntax by dot syntax. For instance, config.flag instead of config["flag"].

Unsupported version control system "git": Can't find an appropriate component, maybe the corresponding plugin was not enabled?

Changing to category "task" since presumably this has no impact on users.
