Well it's not just emacs, there are lots of editor writers that now seem to 
think we need to backup our underware before farting. I hate being treated as a 
windows-user moron and having my disk space spammed with useless copies so the 
first thing I have to do is find out how to turn these features off.

However, in the case of a trivial edit to a config file as discussed here, I 
find it much simpler to dupe the original LINE rather than the file, comment 
out the dupe and make my new settings. Having the original line just above is 
more useful and does not create a new file for the sake of a 16 byte diff.

Added bonus of this least change strategy is not making bogus configuration 
scripts in important directories. ;)
