tcsh estranheza variável

Question

O que faz com que tcsh ignore caracteres depois de \ fa?

% set funky = "'perl -e 'print pack q(c*), 9,247..255''"
% echo "$funky" | od -x
0000000 f709 f9f8 fbfa fdfc fffe 000a
0000013
% set funky = "'perl -e 'print pack q(c*), 10,247..255''"
% echo "$funky" | od -x
0000000 f8f7 faf9 000a
0000005

csh não:

% set funky = "'perl -e 'print pack q(c*), 9,247..255''"
% echo "$funky" | od -x
0000000 f709 f9f8 fbfa fdfc fffe 000a
0000013
% set funky = "'perl -e 'print pack q(c*), 10,247..255''"
% echo "$funky" | od -x
0000000 f8f7 faf9 fcfb fefd 0aff

% tcsh --version
