Have list hashes depend on the order of the contents, as is the case for vectors.
src/ChangeLog addition:
2008-01-16 Aidan Kehoe <kehoea@parhasard.net>
* elhash.c (internal_hash):
Make short lists with the same contents in a different order hash
distinctly. Gives better performance for things like three-element
lists describing colours. Thank you Sebastian Freundt!
tests/ChangeLog addition:
2008-01-16 Aidan Kehoe <kehoea@parhasard.net>
* automated/hash-table-tests.el:
Assert that two short lists with the same contents in distinct
orders hash differently.
