The context is: there is a file name containing a $, and it is listed
on the RHS of a dependency line:
and I would strongly expect that $$file to yield a string "$file" not
be expanded arbitrarily often. Why does it happen to be
that works here, and not, say, $$$$$file ?
I understand that the handling in general is tricky and of course we often
need to create variables as result of expansions.
