How can I have a command auto-run when a file is opened from 'desktop
recovery' please? I want to auto-run "M-x linum-mode" when I open my
daily journal, which stays open all the time. Running that command will
switch off linum-mode for that file, which may stop "file-rot" that I
have observed in the past. This can, at present, only be resolved by
shutting down emacs for half an hour or so, and then restarting it,
and normal functionality will have been restored.

Thanks
Sharon.
