Root: huge optimisation (and security feature) for VCS directories
If under root user, for VCS directories we do not collect anymore the VCS status information. Before it was collected (even if LP_ENABLE_VCS_ROOT=0, which is the default) but just not displayed. This is a huge optimisation for VCS directories, and also a security feature, as our shell code is absolutely not resistant to specially crafted VCS content.
