Thinking about this more, I'd be very surprised as a `git` user if introducing a new config option broke backwards compatibility. Other `git` UIs have mixed support for slashes in remote names: * GitHub Desktop has an open issue regarding remote names that contain slashes: https://github.com/desktop/desktop/issues/3618 * Sublime Merge (as-of build 2032) renders remote names with slashes as a tree of remotes, e.g.: $ git remote -v foo/bar /tmp/example_repo foo/baz /tmp/example_repo2 is rendered with as a collapsible tree, roughly: REMOTES (2) v foo bar baz * `tig` (2.4.1) renders remote names with slashes identically to those without slashes Retroactively tightening those rules would cause more harm than good (both for end-users and for downstream projects), especially with no safe way to fix existing /-containing remote names. I'm going to keep the multilevel check out of this patchset (thus continuing to allowing multilevel remote names), but if anyone feels strongly either way please let me know! :) Sean
