I may be daft but I believe I recall that long ago, that is how you checked
files in and out. If the file was not checked out and you edited it, it would
be read-only. And to toggle that, you could do ^X-^Q and that would trigger
emacs into checking out the file. Thus, the warning when that procedure
changed to alert people that things have changed.
