[Gprename-users] Instead of eliminating, it duplicate characters.

[Mario M. <mar...@gm...>]

Hi, there. If I want to remove the last character of the file name, I 
supposed to use negative numbers to achieve that. But, instead of doing 
that, it duplicate characters. Like this capture:

Also, by using positive numbers in the second field, it duplicates that 
number of characters:

Is this a bug? Is there any other way to achieve it?

Thanks.
