Just say "export

Yup, both of those solutions work, though I'm sticking
with exporting 
SHELL for portability. I don't have tcsh installed.

Out of interest, is it correct behaviour for Bash to
return a value for 
SHELL even though it hasn't been explicitly set?
Presumably this is 
handled by Bash itself in such a way that getenv
doesn't see it; is that 
in itself a bug?
