[Fab-user] @needs_host decorator trashes function signature on functions it decorates

[Matthew Wilson]

Hi --

Initially, the get function looks like this when defined:

@needs_host
def get(remote_path, local_path):
    """
    Download a file from a remote host....
    """

But after needs_host has its way with it, those helpful parameter
names are replaced by *args and **kwargs:

>>> from fabric import api
>>> import inspect
>>> inspect.getargspec(api.get)
([], 'args', 'kwargs', None)

There's a decorator module [1] I'm fond of that preserves the function
signature.  Might you accept a patch that uses that?  Fabric would
have to include that module as a dependency.
