For example, in the following master branch, I need to trash just the commit af5c7bf16e6f04321f966b4231371b21475bc4da, which is the second due to previous rebase:

```
commit 60b413512e616997c8b929012cf9ca56bf5c9113
Author: Luca G. Soave <luca.soave@gmail.com>
Date:   Tue Apr 12 23:50:15 2011 +0200

    add generic config/initializers/omniauth.example.rb

    show github user info if logged

    add multiple .container at blueprint layout

commit 414ceffc40ea4ac36ca68e6dd0a9ee97e73dee22

Date:   Thu Apr 21 19:55:57 2011 +0200

    add %h1 Fantastic Logo + .right for 'Sign in with Github'

```

I need to mantain 

* the First commit 60b413512e616997c8b929012cf9ca56bf5c9113,
* the Third commit e6523efada4d75084e81971c4dc2aec621d45530 and
* the Last commit 414ceffc40ea4ac36ca68e6dd0a9ee97e73dee22

"throwing away" just the Second commit **af5c7bf16e6f04321f966b4231371b21475bc4da**

How can I do that?
Thanks in advance 
Luca
