It didn't do the editing "inline", it created a new file and renamed the
old one ".bak". In other words, on Cygwin "-i" is really "-i.bak". If
you try the above sequence on linux you don't get a .bak file and the
changes are truly done in-place. I assume this relates to differences
in filesystem semantics.
