Good point. Maybe a hybrid check which includes the /usr/share/misc/magic test and a check for the existance of the segments could be used. I dont know what segments are mandatory in a core file and it could be a truncated file so maybe this is not a good idea. Assuming the user knows what they are doing along with the magic test should be enough.
