extensions: copy extra __dict__ of original function
Future patches will make @command decorator set properties such as "norepo" to
a function object. This patch makes sure these properties never be lost by
wrapcommand() or wrapfunction().
This change won't be crazy as the standard functools.wraps() copies __dict__.
