Make variable replacements open a can of worms. Sometimes they should

VS variables cause problems. In order to pass the referenced value

with spaces the reference must be quoted. If the variable value ends

in a backslash then it will escape the ending quote! In order to make

the ending backslash appear we need this:

However if there is not a trailing backslash then this will put a

quote in the value so we need:

Make variable references are platform specific so we should probably

just NOT quote them and let the listfile author deal with it.
