Summary: glob.glob inconsistent about broken symlinks

Initial Comment:
`glob.glob()` uses `os.listdir()`, which includes
borken symlinks in the listing if the pattern contains
shell metacharacters but 
uses `os.path.exists()` which is False for broken
symlinks if the pattern is a fixed name.  Thus:

>>> os.symlink('broken', 'sym1')
>>> os.symlink('broken', 'sym2')
>>> import glob
>>> glob.glob('sym*')
['sym1', 'sym2']
>>> glob.glob('sym1')
[]
>>> glob.glob('sym2')
[]

This bug exists in all versions of the module since its
creation up to 2.4.

The correct behaviour (judging by the shell's behaviour -
that's the model for the module, isn't it), is to always
include  broken symlinks in the results.

Several fixes for this bug are provided by patch 941486
(http://python.org/sf/941486).  
[They all include the testcase attached here.]
