DOC: DataFrame MERGE Example

[SplashDance]

In the Docstring for the Merge method, the example provided:

merge(A, B, left_on='lkey', right_on='rkey', how='outer')  

returns a sorted DataFrame. Thus, we need to either add a sort=True kwarg to the above code or replace the purported output with the actual (unsorted) output:

  lkey  value_x rkey  value_y
0  foo        1  foo        5
1  foo        4  foo        5
2  bar        2  bar        6
3  bar        2  bar        8
4  baz        3  NaN      NaN
5  NaN      NaN  qux        7

@SplashDance Thanks for the report! Would you like tro try to change this in the docstring (do a PR)? If you need some help with that, we would like to assist! (see here for some basic docs: http://pandas.pydata.org/developers.html#working-with-the-code)

For the basic example, I think it would be better to provide the actual output without the sort kwarg. (And BTW, edding the code to construct A and B would also be welcome).

I've fixed the code--that was the easy part--but I'm not exactly sure how to proceed. Trying to learn about GitHub makes my head hurt... @jorisvandenbossche: Can you tell me how I can proceed?

@SplashDance The commit is looking good! Normally you should now see somewhere a button 'make a pull request'
