Assume that I am working with a file whose name contains a unique version number for example
03jhcjh.tex and so on. Currently I create a new version of the file by
C-x C-w and incrementing the number manually.
To be precise I would like to maintain the number length if possible, i.e. 027 → 028 instead of 28, but 9 → 10.
Is there a function in emacs which automatizes this procedure? Other solutions are welcomed.
