Oh, that would indeed be a great option ("keep .orig files")! It could be 
orthogonal to any other backup strategy, but you would get one more file on 
disk for each modified file.

(ATM, I manually try to do that for all system config files (admittedly, I 
don't use KDE programs to edit /etc files..) which makes it easier to guess 
the amount of work needed to bring a fresh system installation into shape.)

That brings up another idea:  AFAICS, the preferred backup strategy varies 
from task to task.  So far, it has been proposed to have application-wide 
settings for the strategy (e.g. one "normal" ~ file system-wide, but numbered 
for Krita).  How about choosing the strategy based on file name+path?

E.g. numbered for "*.kwd", "~/Thesis/*", and "*important*"?

I always found the concept of numbered backups interesting, but did not want 
to have hundreds of backup files on my system (which arise if you use them 
unconditionally)..
