If your "problematic" commit contains only that "large file" and nothing 
else, then you'd probably like to remove the whole commit instead of 
editing it (as Peter described). Just do:

$ git rebase --interactive problematic^

Again, notice the ^ after "problematic"

An editor pops up with the history since problematic's parent, i.e. 
"problematic" is the first item in the list. Simply delete the line with 
the "problematic" commit. It should be the first line. Save the file, 
exit the editor. That's it.
