+The official config is now `command-templates.log`, the historical
+`ui.logtemplate` is a valid alternative for it.

+When both are defined, The config value read the last "win", this should keep
+being true if the config have other alias. In other word, the config value read
+earlier will be considered "lower level" and the config read later would be
+considered "higher level". And higher level values wins.
