Readline and unwanted filename completion

[Simon Budig]

Hi all.

Something is broken with the completion of readline:

simon at ping-pong:~$ python
Python 2.1.1+ (#1, Jan  8 2002, 00:37:12) 
[GCC 2.95.4 20011006 (Debian prerelease)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> import rlcompleter
>>> rlcompleter.readline.parse_and_bind ("tab: complete")
>>> foo<TAB><TAB>
foo.gif     foo.txt     foo2.gif    foobar.jpg
>>> foo.gif
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
NameError: name 'foo' is not defined

[the "foo.gif", "foo.txt", "foo2.gif" and "foobar.jpg" are files
in my current working directory]

It seems that readline has a fallback to filename completion when
no matches are available. Even if I use my own completion function:

>>> def nullcompleter (text, state):
...    print "\nBuh!"
...    return None
... 
>>> rlcompleter.readline.set_completer(nullcompleter)
>>> foo<TAB>
Buh!
<TAB>
Buh!

foo.gif     foo.txt     foo2.gif    foobar.jpg  foot        
>>> foo

there is this filename fallback.

Is this a known Problem? Is there an evil hack to avoid this?

Thanks,
        Simon
