Tabs versus Spaces in Source Code

True! but normally if I'm editing someone else's code then I'm only
making small changes and so can't be bothered to temporarily cripple my
editor. If I'm merging my code with someone else's space-indented code
then piping through sed 's/TAB/SPACES' does the trick.
