Missing completion on io:

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Writing io:<M-?>

What is the expected output? 
"Possible completions are:
columns     format  fread   fwrite
get_chars   get_line    get_password    nl
parse_erl_exprs     parse_erl_form  put_chars   read
request     requests    rows    scan_erl_exprs
scan_erl_form   setopts     write"

What do you see instead?
There are no completions.

What version of the product are you using? On what operating system?
Both distel from SVN revision 89 and the Xmas edition gives me this.
erl -version == Erlang (SMP,ASYNC_THREADS) (BEAM) emulator version 5.6.3
Ubuntu 8.10.

Possible fix? I don't know if this is preferable or not.
$ svn diff distel.erl
Index: distel.erl

This fixes the problem for me. But maybe it breaks something else I don't
know about.

 works for me. please try (in the erlang shell);
distel:functions(io,"").

 should print;

{ok,["columns","format","fread","fwrite","get_chars",
     "get_line","nl","parse_erl_exprs","parse_erl_form",
     "put_chars","read","rows","scan_erl_exprs","scan_erl_form",
     "setopts","write"]}

• Changed state: Started

[GoogleCodeExporter]

distel:functions(io, "").
{ok,[]}

distel:functions(rpc, "").
{ok,["abcast","async_call","block_call","call","cast",
     "code_change","eval_everywhere","handle_call","handle_cast",
     "handle_info","init","multi_server_call","multicall",
     "nb_yield","parallel_eval","pinfo","pmap",
     "safe_multi_server_call","sbcast","server_call","start",
     "start_link","stop","terminate","yield"]}

Also tried installing Erlang from source, including erlang-mode. Same result.
