Check if repository exists

From: Goffredo Baroncelli <[e-mail]>
Subject: Re: Trivial: in remoterepository.__init__ check if the repository
        exist

I hope that this is correct :-)

Another typo, another patch, tank to Peter Stamfest and Radoslaw Szkodzinski.

The patch is trivial: adds a check in the body of the init method of the
+remoterepository
class. Before if the path didn't exist, hg would not raise any error.

Test manually performed after the patch has been merged:

test:                                                     result
create a new repository from another local repository     OK ( no problem )
create an empty repository                                OK ( no problem )
pull from a not existent repositary                       OK ( raise an error )

(error message tweaked by mpm)
