This is an obvious candidate for hiding behind one of the options like
CSH_JUNKIE_STUFF_THAT_NO_ONE_COULD_CONCEIVABLY_WANT_ANY_MORE on the
grounds of consistency --- it's hard to see how sending the error to
stder could make anything other than a script/function deliberately set
up to expect csh output any more confused --- though I'm not that set on
the option name.
