Without a / prefix in the original ssh path, the path becomes
relative to whatever the ssh server wants, usually the user's
$HOME. I.e., they do not refer to the same path on the remote
system.

  alice at example.com:/foo.git -> ssh://alice@example.com/foo.git
  alice at example.com:foo.git -> ssh://alice@example.com/home/alice/foo.git (or something else!)

The path in an ssh:// uri is absolute, so the relative case must
be handled differently. But it's easy, git supports ~ expansion,
like:

  alice at example.com:foo.git -> ssh://alice@example.com/~/foo.git
