[gcmd-dev] safe advrename

[Michael]

Just to ensure - what exactly is advrename doing when there are already files 
with the same name ? 

When you renumber

        file-01
        file-02
        file-03

        to 

        file-02
        file-03
        file-04


it will rename only file-03 to file-04. 

So it appears only those are renamed which are 'possible' w/o overwriting any 
file. 
Is that waterproof and solid as rock ;) ?

Such a case is almost always an error on the users side so she wants to correct 
the template. But after such a mis-naming, files which were already in some 
order often are totally screwed. So what would be done, in the ideal world we 
don't live in ? The renaming would only be 'simulated' (with those problem 
cases highlighted in red) and a popup would ask 'Some files can not be renamed. 
Do you really want to continue ?' and then you can choose 'continue without 
overwriting any file' (may we make that 'do what is possible' ?) and 'Cancel' 
('Lemme try again!!').

Now since we've more serious things to talk about, this is not a feature 
request. It's just for the records.
