This series is based on ds/sparse-list-in-cone-mode.

This series attempts to clean up some rough edges in the sparse-checkout
feature, especially around the cone mode.

Unfortunately, after the v2.25.0 release, we noticed an issue with the "git
clone --sparse" option when using a URL instead of a local path. This is
fixed and properly tested here.

Also, let's improve Git's response to these more complicated scenarios:

 1. Running "git sparse-checkout init" in a worktree would complain because
    the "info" dir doesn't exist.
 2. Tracked paths that include "*" and "\" in their filenames.
 3. If a user edits the sparse-checkout file to have non-cone pattern, such
    as "**" anywhere or "*" in the wrong place, then we should respond
    appropriately. That is: warn that the patterns are not cone-mode, then
    revert to the old logic.

Updates in V2:

 * Added C-style quoting to the output of "git sparse-checkout list" in cone
   mode.
 * Improved documentation.
 * Responded to most style feedback. Hopefully I didn't miss anything.
 * I was lingering on this a little to see if I could also fix the issue
   raised in [1], but I have not figured that one out, yet.

Update in V3:

 * Input now uses Peff's recommended pattern: unquote C-style strings over
   stdin and otherwise do not un-escape input.
