Speaking for web2c/kpathsea:

A hash lookup will first retrieve a list of directories in which a
certain file resides. Then, this list is matched against the search path
components (in this matching, the *whole* list is matched against each
search path; one by one). The result is that the order of search path
components is always followed even if ls-R hashing is used.

So, if your search path is
then always the newstuff will have precedence. Of course,
gives unspecified behaviour.
