One possible way to avoid this particular problem, at least if you're
hacking with text files instead of GUI dialogs, is to copy the file
with a date-based name as Chuck suggested, or use the Revision Control
System (rcs). If it's not installed by default, it's almost certainly
available through the package manager of your distribution of choice.
Running:

  ci -l <filename>

will put the file into a simple revision control system. See the man
pages for rcsintro(1), rcs(1), ci(1), and co(1) for more details, but
if you make only one change, or a small set of changes at a time, then
check in the file and test the new configuration, you can revert to a
known-good copy if something goes wrong.
