Obviously, = though, this doesn't work on make files. I picked up this little piece = of code from an emacs wizard friend and have never revisited it. So, is this a bug or is the untabify command no longer supported? If = it's now a bug, this should now be reproducible. If it's an obsolete = package, do you have any suggestions for a replacement?
