I see your patch as an improvement too. status is a bit expansive, but
you hit this portion of code only when trying "rebase" by mistake, so
it's acceptable to let git take a bit of time to explain your mistake.

That said, I think it's still worth making the messages of
"update-index" a little more verbose and consistant with "status" (my
previous patch), since I think there are other occurences of
user-visible output of update-index in porcelain git.

Ideally, update-index would be a C function returning a struct
containing all the information about the status, with a function
is_clean(...) and another print_as_status(...), to allow the same
functionality with better performances, but I won't have time to do
this.
