Now there seems to be no trouble anymore.

Hard to say. I've logged things like mergemaster by the script command. Until 
7.2 I just found messages like

./etc/csh.cshrc and installed have the same CVS Id, deleting

so I can't exactly track when this first appeared in csh.cshrc. (Maybe it's a 
good idea to trace changes of etc in a version control system from time to 
time.)

Would be nice.
