hmm... the script should continue not terminate.

at this point it is difficult to tell apart which is a bug or a
feature. there are subtle differences between csh and tcsh and some
what argue that both are equally broken. i am not going down that
rabbit hole, but very obviously the script has only seen limited
testing on a "real" csh.

i also would like to point out another option: use the /bin/sh
compatible version of the launcher script. the bourne shell on ubuntu
is very standard conforming and thus chances are that it has less of
an issue...
