Some display fixes in hashtable.c

[Zefram <A.Main@xxxxxxxxxxxxxxxxx>]

-----BEGIN PGP SIGNED MESSAGE-----

One of my recent patches broke a couple of display formats in hashtable.c.
The symptoms are that command hash table entries lose their filename
(sometimes garbage appears instead), and array values as output by "set"
look like "foo=(bar bazquux )" instead of "foo=(bar baz quux)".
