+    #  * If you know that "x" is a bookmark, use repo._bookmarks.changectx(x)
+    #  * If you know that "x" is a tag, use repo[repo.tags()[x]]
+    #  * If you know that "x" is a branch or in some other namespace,
+    #    use the appropriate mechanism for that namespace
+    #  * If you know that "x" is a hex nodeid prefix, use
+    #    repo[scmutil.resolvepartialhexnodeid(repo, x)]
+    #  * If "x" is a string that can be any of the above, but you don't want
+    #    to allow general revsets (perhaps because "x" may come from a remote
+    #    user and the revset may be too costly), use scmutil.revsymbol(repo, x)
