Subject: 24.5; all-completions returns duplicates for Info-read-node-name-1

To reproduce, eval this in the top *info* directory:

(setq x (all-completions "(" 'Info-read-node-name-1))

x will contain many duplicates for each node, like "org" "org" "org"
"org" "org.info.gz" "org" "org.info.gz" "org" "org.info.gz".

Finally, if one of the elements of `all-completions' is passed, it still
doesn't work. I'm guessing that it expects "(org)" instead of "org", but
then why not offer these on the completion list?
