man/ChangeLog addition:
2010-01-09 Aidan Kehoe <kehoea@parhasard.net>
* lispref/objects.texi (Hash Table Type):
* lispref/hash-tables.texi (Introduction to Hash Tables):
Use keywords, not ordinary symbols, in the hash table read syntax;
document that we do accept the ordinary symbols for the sake of
backward-compatiblity.

* elhash.c:
(print_hash_table, print_hash_table_data)
(hash_table_instantiate)
(structure_type_create_hash_table_structure_name):
(syms_of_elhash):
Use keywords, not ordinary symbols, in the hash table read syntax,
for compatibility with Common Lisp and recent GNU Emacs. Accept
the non-keyword syntax, but don't allow mixing of the two styles.
