The first step of an interactive rebase is to generate the so-called "todo script", to be stored in the state directory as "git-rebase-todo" and to be edited by the user. Originally, we adjusted the output of `git log <options>` using a simple sed script. Over the course of the years, the code became more complicated. We now use shell scripting to edit the output of `git log` conditionally, depending whether to keep "empty" commits (i.e. commits that do not change any files). On platforms where shell scripting is not native, this can be a serious drag. And it opens the door for incompatibilities between platforms when it comes to shell scripting or to Unix-y commands. Let's just re-implement the todo script generation in plain C, using the revision machinery directly. This is substantially faster, improving the speed relative to the shell script version of the interactive rebase from 2x to 3x on Windows. Note that the rearrange_squash() function in git-rebase--interactive relied on the fact that we set the "format" variable to the config setting rebase.instructionFormat. Relying on a side effect like this is no good, hence we explicitly perform that assignment (possibly again) in rearrange_squash().
