Allow git-annex to recognise repo as an annex-capable remote

[mih]

Its own test fails like this:

$ git annex init --debug       
...
[2018-09-26 11:53:56.198970849] Request {
  host                 = "web.gin.g-node.org"
  port                 = 443
  secure               = True
  requestHeaders       = [("Range","bytes=0-"),("Accept-Encoding","identity")]
  path                 = "/INT/multielectrode_grasp/config"
  queryString          = ""
  method               = "GET"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault
  requestVersion       = HTTP/1.1
}

it would be so lovely if publicly provided data was publicly accessible via git-annex directly, at least for download

Thanks for the comment. We've been making some internal and client-side changes to the whole GIN workflow and infrastructure and I've been meaning to review the these issues. We'd like to open up GIN repositories to make them more accessible and interoperable.

I'll get back with specifics once I start reviewing, but feel free to leave more comments on the kind of availability you'd like to see.

the ultimate use case is just to be able to access data via regular http/https, e.g.

• [x] git clone https://web.gin.g-node.org/hbridge_oxford/brainwithoutv1; cd brainwithoutv1
• [ ] git annex get *

and then datalad users would be able to just datalad install -g https://web.gin.g-node.org/hbridge_oxford/brainwithoutv1
