The typical usage pattern would be to run a test (or simply a compilation
command) at given points in history.
The shell command is ran, and the rebase is stopped when the command
fails, to give the user an opportunity to fix the problem before
continuing with "git rebase --continue".

The name of the command may be subject to discussions. I've chosen
"run", but maybe "shell" would be OK too. In both cases, it doesn't
allow the one-letter version since both "r" and "s" are already used.

-----------------------------
+Reordering and editing commits usually creates untested intermediate
+steps. You may want to check that your history editting did not break
+anything by running a test, or at least recompiling at intermediate
+points in history by using the "run" command. You may do so by
+creating a todo list like this one:
+
+-------------------------------------------
+pick deadbee The oneline of this commit
+run make
+pick c0ffeee The oneline of the next commit
+run make test
+...
+-------------------------------------------
+
+The interactive rebase will stop when a command fails (i.e. exists
+with non-0 status) to give you an opportunity to fix the problem. You
+can continue with `git rebase --continue`.
