Looks like it does not support specifying paths stored in [paths] config, like hg perfdiscovery default says 'repository default not found'.

@pulkit indeed, I didn't think of that, seems like a good idea, thanks.
I wouldn't go as far as putting path=default by default, though, so that users don't start hammering providers unwillingly.
