hi! thanks for your answers!
I didn't knew about --amend for commit, will certainly use it...
however it seems that I get missunderstood...
A-o-o-o-o-o-B-o-o-o-o-C
                      \-o-o-D-/
let say I have the above tree, o are temporary unbuildable commits, A B 
C D are usable versions
I want as posteriory remove the o to get the following tree
A-B---C
     \-D/
in fact I just wanna clean a little my tree since I forgot to amend ;)
is this possible?
ok I know, the best is to prevent! not to cure! so I'll amend ;)
thanks
