Serialise non-default hash table rehash thresholds correctly; use this.
src/ChangeLog addition:
2009-12-17 Aidan Kehoe <kehoea@parhasard.net>
* elhash.c (HASH_TABLE_DEFAULT_REHASH_THRESHOLD):
New macro, giving a default value for a hash table's rehash
threshold given its size and test function.
(print_hash_table): Print the hash table's rehash threshold if it
has a non-default value. Ditto for its rehash size.
(Fmake_hash_table): Supply the keyword arguments in a format
understood by #'function-arglist.
lisp/ChangeLog addition:
2009-12-17 Aidan Kehoe <kehoea@parhasard.net>
* mule/make-coding-system.el
(fixed-width-create-decode-encode-tables):
Use a rehash threshold of 0.999 for this hash table, now that hash
table rehash thresholds are serialised correctly; these hash
tables will never be resized, and it's not even that important
that they are *that* fast, for most of the coding systems they're
used a minority of the time.
