The documentation shown is just one line, but the echo area is resized
to a height of two chars, so a line is wasted and the size of the echo
area is changing back and forth every time the point moves. Maybe there
is a trailing newline wanting to be stripped out for good. Forcing eldoc
to never resize the echo area would not be a nice solution.

I cannot replicate this issue with Python 2.7.6 and Python 3.4.0

Given the following example file:

        from urlparse import urlparse
    except ImportError:
        from urllib.parse import urlparse


    def afunction(a, b, c=3, d=None):

Sending it with `python-shell-send-buffer` and then enabling eldoc-mode.

The observed behavior is:

  1. Placing the cursor over "urlparse", echo area displays "Parse a URL
  into 6 components:", without extra newline.

  2. Placing the cursor over "afunction", shows the signature of the
  function without extra newlines.

I'm closing this one, if you have a proper recipe, please re-open with
