Please describe the problem.

I was trying to follow https://git-annex.branchable.com/special_remotes/git-lfs/ (only without any encryption), to store at least some data on github via LFS (e.g., for https://github.com/dandi-datasets/nwb_test_data).

Even though I do provide URL to the annex initremote call, it is not stored within remote.log:

$> sudo rm -rf /tmp/testds2 && ( mkdir /tmp/testds2 && cd /tmp/testds2 && git init && git annex init && git annex initremote gh-lfs autoenable=true type=git-lfs url=git@github.com:yarikoptic/testds2.git encryption=none && git show git-annex:remote.log; )                                                                                  
Initialized empty Git repository in /tmp/testds2/.git/
init  (scanning for unlocked files...)
ok

initremote gh-lfs ok

git annex 7.20190912-1~ndall+1

If I just proceed, populate and copy some data via lfs (example uses datalad's create-sibling-github to create a new repo):

$> ( cd /tmp/testds2 && touch 123 && git annex add 123 && git commit -m 'add 123' && datalad create-sibling-github -s origin testds2 && git push -u origin master && git annex copy --to=gh-lfs 123; git push origin git-annex; )                                                                                       
add 123

on a new clone I get a complaint that url= is missing, and no data is fetched

Invalid command: 'git-annex-shell 'configlist' '/~/yarikoptic/testds2.git''
  You appear to be using ssh to clone a git:// URL.
  Make sure your core.gitProxy config option and the
  GIT_PROXY_COMMAND environment variable are NOT set.

  Remote origin does not have git-annex installed; setting annex-ignore

  This could be a problem with the git-annex installation on the remote. Please make sure that git-annex-shell is available in PATH when you ssh into the remote. Once you have fixed the git-annex installation, run: git annex enableremote origin
(Auto enabling special remote gh-lfs...)

  Specify url=

get 123 (not available) 
  Try making some of these repositories available:
    92ce3cfc-8c58-42db-8aa3-ea4d4b3a6011 -- yoh@hopa:/tmp/testds2
    c9132e68-e9d8-40b5-ba34-5d60a8b9c844 -- gh-lfs

  (Note that these git remotes have annex-ignore set: origin)

git-annex: get: 1 failed

so I had to enableremote it while providing URL I become able to get the file:

$> git annex enableremote gh-lfs autoenable=true type=git-lfs url=git@github.com:yarikoptic/testds2.git encryption=none && git annex get 123                                         
enableremote gh-lfs ok      
(recording state in git...)
get 123 (from gh-lfs...) 
(checksum...) ok
(recording state in git...)

Shouldn't that URL be recorded in remote.log? (similarly to type=git remotes)
