Improve error messages for running git clone against a Mercurial repository
Summary:
Fixes T11938.
Note that there's a subcase here: if you hg clone or svn checkout a short /source/ URI that ends in .git, we miss the lookup and don't get this far, so you still get a generic error message.
Hopefully it is clear enough on its own that proto://.../blah.git is, in fact, a Git repository, since it says ".git" at the end.
If that doesn't prove to be true, we can be more surgical about this.
Test Plan:
$ git clone ssh://local@localvault.phacility.com/source/quack.notgit/ Cloning into 'quack.notgit'... phabricator-ssh-exec: This repository ("quack.notgit") is not a Git repository. Use "hg" to interact with this repository. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
$ hg clone ssh://local@localvault.phacility.com/source/phabx remote: phabricator-ssh-exec: This repository ("phabx") is not a Mercurial repository. Use "git" to interact with this repository. abort: no suitable response from remote hg!
