Error cloning a Git repository on Heroku

[look]

Cool plugin. I got it working for a GitHub repository, but when I tried cloning one from Heroku I got the following error. Heroku says I'm fetching an invalid path.

When I use git to clone the repository with the same Git URL it works. Anyone get this working? I know this usage is probably kind of non-standard. ;)

hg gclone git@heroku.com:repository-name.git
fetching from : origin

Invalid path.
Syntax is: git@heroku.com:<app>.git where <app> is your app's name

This alone won't work, because hg-git adds a leading slash to the repo name, and Heroku doesn't like that. One of these days, I'll make the path-parsing function generic enough to understand both Github-style and Heroku-style paths. In the meantime, since I only have to push to Heroku once every few weeks, I just qpush and qpop this patch in my hg-git repo for that one special case:

diff --git a/git_handler.py b/git_handler.py
--- a/git_handler.py
+++ b/git_handler.py

                     host = 'git@' + host
                 else:
                     host, path = uri[len(handler):].split("/", 1)
-                return transport(host), '/' + path

         return SubprocessGitClient(), uri

Using the current version I am able to push to Heroku using a URL like this:

hg push git+ssh://git@heroku.com:your-app-name.git

Cloning works too.

The workaround proposed by 'look' stops working with Mercurial 2.0 (at least). hg-git adds a trailing slash to the repository path, which is not expected by Heroku.
