git_handler: detect and reject nested Mercurial repositories The ReviewBoard repository contains a Mercurial repository within its Git repository; if you just convert that into Mercurial, you can't check it out. We handle this similar to invalid Git paths: by default, refuse the conversion, but with a configuration knob to force it through with a warning.
