Checking the missing commits after expansion makes sense (but it is only
a matter of adding "| git rev-list --no-walk --stdin" somewhere in the
pipeline).

But IMHO, checking the syntax errors is better done as early as possible
if you want accurate error messages. This way you still have what the
user typed available.
