rebase -i: fix misleading error message after 'exec no-such' instruction
When the todo sheet of interactive rebase instructs to run a non-existing command, the operation stops with the following error: Execution failed: no-such You can fix the problem, and then run git rebase --continue fatal: 'rebase' appears to be a git command, but we were not able to execute it. Maybe git-rebase is broken? The reason is that the shell that attempted to run the command exits with code 127. rebase--interactive just forwards this code to the caller (the git wrapper). But our smart run-command infrastructure detects this special exit code and turns it into ENOENT, which in turn is interpreted by the git wrapper as if the external command that it just executed did not exist. This is finally translated to the misleading last two lines in error message cited above. Fix it by translating the error code before it is forwarded.
