Bug#994026: xkb-data: breaks Multi_key, a.k.a. Compose key

[Vincent Lefevre <vincent@vinc17.net>]

Package: xkb-data
Version: 2.33-1
Severity: important

The upgrade from 2.29-2 to 2.33-1 silently breaks Multi_key.

A diff of the xkbcomp dump gives in particular:

     key <RALT> {
-        type= "TWO_LEVEL",
-        symbols[Group1]= [ ISO_Level3_Shift,       Multi_key ]
+        type= "ONE_LEVEL",
+        symbols[Group1]= [ ISO_Level3_Shift ]
     };

i.e. Multi_key is no longer there.

Note: I use the gb keyboard layout.
