Call Tips are floating windows which display function, class, and method
parameter and docstring information when you type an opening parenthesis, and
which disappear when you type a closing parenthesis.

If there is a Python subprocess, get the calltip there. Otherwise,
either this fetch_tip() is running in the subprocess or it was
called in an IDLE running without the subprocess.
The subprocess environment is that of the most recently run script. If
two unrelated modules are being edited some calltips in the current
module may be inoperative if the module was not the last to run.
To find methods, fetch_tip must be fed a fully qualified name.

a� Return a string describing the signature of a callable object, or ''.
For Python-coded functions and methods, the first line is introspected.
Delete 'self' parameter for classes (.__init__) and bound methods.
The next lines are the first lines of the doc string up to the first
empty line or _MAX_LINES. For builtins, this typically includes
the arguments in addition to the return value.
