This should, in fact, be:    
    
    $ git checkout featureA
    $ git commit
    $ git checkout master
    $ git reset --hard HEAD^
    $ git merge <HEAD@{1} parents>
    
(removed "git add" step, as that is needed for proposed single step 
solution as well, as a usual step preceding the commit; also replaced 
concrete branch names in the last step with a more generic 
description, better communicating real intent)

Here, the diagram should look like this:

(3)      o---o---o---\ (featureA)
        /             \
    ---o---o---o-------M'' (master, HEAD)
        \             /
         o---o---A''-o (featureB)

(replaced leftover M' from the previous diagram with M'' to show it`s 
yet another (updated) merge commit, different from both M and M' in 
terms of SHA1, yet the contents would probably, but not necessarily, 
be the same for all three; same for leftover A', replaced with A'')
