You can just add

bug#18794: 24.4; python mode eldoc unnecessarily resizes echo area

[Carlos Pita]

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.

bug#18794:

[Carlos Pita]

Maybe it would be nice to replace some trailing punctuation too, like colons in

In [21]: urlparse.__doc__
Out[23]: "Parse a URL into 6 components:\n
....

True, this is rude from urlparse, but it's a real world example.

bug#18794: 24.4; python mode eldoc unnecessarily resizes echo area

[Fabián Ezequiel Gallina]

I cannot replicate this issue with Python 2.7.6 and Python 3.4.0

Given the following example file:

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

    urlparse

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

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
it.

Could it be related to the fact I'm using ipython as the shell process? If
not I will take a closer look at this later, it's happening in every setup
I'm currently using.

Yes, ipython seems to be the key ingredient for the recipe.
