+git-ls-remote-bundle-uri(1)
+===========================
+
+NAME
+----
+git-ls-remote-bundle-uri - List 'bundle-uri' in a remote repository
+
+SYNOPSIS
+--------
+[verse]
+'git ls-remote-bundle-uri' [-q |--quiet] [--uri] [--upload-pack=<exec>]
+ [[-o | --server-option=]<option>] <repository>
+
+
+DESCRIPTION
+-----------
+
+Displays the `bundle-uri`s advertised by a remote repository. See
+`bundle-uri` in link:technical/protocol-v2.html[the Git Wire Protocol,
+Version 2] documentation for what the output format looks like.
+
+OPTIONS
+-------
+
+-q::
+--quiet::
+ Do not print remote URL to stderr in cases where the remote
+ name is inferred from config.
++
+When the remote name is not inferred (e.g. `git ls-remote-bundle-uri
+origin`, or `git ls-remote-bundle-uri https://[...]`) the remote URL
+is not printed in any case.
+
+--uri::
+ Print only the URIs, and not any of their optional attributes.
+
+--upload-pack=<exec>::
+ Specify the full path of 'git-upload-pack' on the remote
+ host. This allows listing references from repositories accessed via
+ SSH and where the SSH daemon does not use the PATH configured by the
+ user.
+
+-o <option>::
+--server-option=<option>::
+ Transmit the given string to the server when communicating using
+ protocol version 2. The given string must not contain a NUL or LF
+ character.
+ When multiple `--server-option=<option>` are given, they are all
+ sent to the other side in the order listed on the command line.
+
+<repository>::
+ The "remote" repository to query. This parameter can be
+ either a URL or the name of a remote (see the GIT URLS and
+ REMOTES sections of linkgit:git-fetch[1]).

Add a git-ls-remote-bundle-uri command, this is a thin wrapper for issuing protocol v2 "bundle-uri" commands to a server, and to the parsing routines in bundle-uri.c. Since in the "git clone" case we'll have already done the handshake(), but not here, introduce a "got_advertisement" state along with "got_remote_heads". It seems to me that the "got_remote_heads" is badly named in the first place, and the whole logic of eagerly getting ls-refs on handshake() or not could be refactored somewhat, but let's not do that now, and instead just add another self-documenting state variable.
