PATCH: minor stuff

[Peter Stephenson <pws@ibmth.df.unipi.it>]

I noticed that dyncat() was advertised as always using heap memory, whereas
actually it uses ncalloc() which chooses the current sort of allocation.
Since all the uses seem to be in places where the memory doesn't get
explicitly freed, maybe we should change the code to match the comment
(which I probably put there).

While I was doing this I noticed that the hashtable element tablename was
never freed.  It's only used with --zsh-hash-debug.
