It happened in the past with some versions of bash.

However, I think the point is rather that if vim already knows that a
dummy value of the SHELL variable wont work (the empty string is just an
example, a string of spaces would be the same I suppose) then it should
reject it and use a sane default. What do you think?

No need indeed. Does Vim 7 handle as I sketched above the SHELL value?

Thanks,
Cheers.
