strange id and name are assigned for cmapx output if no graph name
It seems %3
is used for map id and map name for cmapx output. Is this intended behavior?
$ echo 'digraph { A -> B }' | dot -Tcmapx -oout.map
$ cat out.map
<map id="%3" name="%3">
</map>
If graph name is given, it is filled correctly.
$ echo 'digraph zzz { A -> B }' | dot -Tcmapx -oout.map
$ cat out.map
<map id="zzz" name="zzz">
</map>
Thanks,
