>Summary: Use of "except:" in modules

Initial Comment:
A large amount of modules in the standard library use
"except:" instead of specifying the exceptions to be
caught. In some cases this may be correct, but I think
in most cases this not true and this may cause
problems. Here's the list of modules, which I got by
doing:

   grep "except:" *.py | cut -f 1 -d " " | sort | uniq

Bastion.py
CGIHTTPServer.py
Cookie.py
SocketServer.py
anydbm.py
asyncore.py
bdb.py
cgi.py
chunk.py
cmd.py
code.py
compileall.py
doctest.py
fileinput.py
formatter.py
getpass.py
htmllib.py
imaplib.py
inspect.py
locale.py
locale.py
mailcap.py
mhlib.py
mimetools.py
mimify.py
os.py
pdb.py
popen2.py
posixfile.py
pre.py
pstats.py
pty.py
pyclbr.py
pydoc.py
repr.py
rexec.py
rfc822.py
shelve.py
shutil.py
tempfile.py
threading.py
traceback.py
types.py
unittest.py
urllib.py
zipfile.py

I've applied the three patches you supplied.

I agree with Martin that to do this right we'll have to
tread carefully. But please go on!

(No way more of this will find its way into 2.1 though.)

inspect.py should be removed from this list, the use is
correct.

In general, I just submitted this bug so that when people
are editing a module they'll notice these things, since in
some cases only someone who knows the code very well can
know if the "expect:" is needed or not.

Can you identify modules where catching everything is
incorrect, and propose changes to correct them. This should
be done one-by-one, with careful analysis in each case, and
may take well months or years to complete.
