-following transient_for. When TRAN_GROUP is found, Client.group will always
-be !NULL. Some smart action should be taken using all members of the group in
-this case.
- Smart action idea:
- Skip over members of the group that are also transients of the group
- (have Client.transient_for set to TRAN_GROUP). These windows are not
- ancestors and using them will also end up causing infinite loops!
+following transient_for. However if it is transient for the group, this
+excludes other windows whom are transient for the group, and windows which
+are children of the window (infinite loops would result)!
