GitHub remote needn't end in .git

[danvk]

Looks like the assumption here is incorrect:

$ github pileup/README.md
Traceback (most recent call last):
  File "/Users/danvk/github/git-helpers/github/github", line 56, in <module>
    repo_url = github.make_github_url(remote)
  File "/Users/danvk/github/git-helpers/util/github.py", line 22, in make_github_url
    assert '.git' in remote
AssertionError
$ git remote -v
origin  https://github.com/hammerlab/internal-tools (fetch)
origin  https://github.com/hammerlab/internal-tools (push)

I guess the .git for a GitHub remote is optional, or perhaps git quietly adds it itself?
