[vdr] little bug in cMenuEditStrItem?

[Markus Hahn]

Hi everybody, 

the issue is found in SetupRecordings->Name instant recording:
If I edit the item an press enter to confirm the change  I stay 
in the actuall  menu, editing mode ist  off. 
On the other hand, if I do not confirm the change an go 
out with kBack I the menu goes to the last parent menu. 

I think  kBack should make the same like kOK without 
remember the changes.

regard Markus
