	inspect.getargspec(obj), test isfunction() directly in pydoc.py instead of trying to indirectly deduce isfunction() in pydoc by virtue of failing a combination of other tests. This shouldn't have any visible effect, except perhaps to squash a TypeError death if there was some path thru this code that was inferring isfunction() by mistake.

"""Generate Python documentation in HTML or text for interactive use.
 | 
						|
 | 
						|
In the Python interpreter, do "from pydoc import help" to provide online
 | 
						|
help.  Calling help(thing) on a Python object documents the object.
 | 
						|
 | 
						|
Or, at the shell command line outside of Python:
 | 
						|
 | 
						|
Run "pydoc <name>" to show documentation on something.  <name> may be
 | 
						|
the name of a function, module, package, or a dotted reference to a
 | 
						|
class or function within a module or module in a package.  If the
 | 
						|
argument contains a path segment delimiter (e.g. slash on Unix,
 | 
						|
backslash on Windows) it is treated as the path to a Python source file.
 | 
						|
 | 
						|
Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines
 | 
						|
of all available modules.
 | 
						|
 | 
						|
Run "pydoc -p <port>" to start an HTTP server on a given port on the
 | 
						|
local machine to generate documentation web pages.
 | 
						|
 | 
						|
For platforms without a command line, "pydoc -g" starts the HTTP server
 | 
						|
and also pops up a little window for controlling it.
 | 
						|
 | 
						|
Run "pydoc -w <name>" to write out the HTML documentation for a module
 | 
						|
to a file named "<name>.html".
