+    ntp: keep original source IP address
+    
+    When an added source is specified by IP address, save the original
+    string instead of formatting a new string from the parsed address, which
+    can be different (e.g. compressed vs expanded IPv6 address).
+    
+    This fixes the chronyc sourcename command and -N option to print the IP
+    address exactly as it was specified in the configuration file or chronyc
+    add command.
