emacs -Q

C-x C-f some-versioned-unmodified-file
do some edition
C-x C-s (the VC status modeline indicator changes from `-' to `:')
undo previous edition
C-x C-s

Now you just turned the file to its original state and is unmodified as
far as the version control system is concerned, but the VC modeline
keeps showing `:' (for example Bzr:836) indicating that the file is
edited. After saving a versioned file, VC should check if the VC backend
flags the file as edited and update the modeline accordingly.
