I agree.  My Tcl is rusty :)

I don't mind large reindents in a situation like this.
I think the resulting code would be better.
It is up to you, though; I also don't mind the status quo.

Pedro> -proc altivec_abi_tests { extra_flags force_abi } {
Pedro> +proc altivec_abi_tests { prefix extra_flags force_abi } { with_test_prefix $prefix {

I think newlines and reindentation would result in prettier code.
The size of the diff is secondary to me; just because we'll have to read
and edit the result, not the patch.

Pedro> -    altivec_abi_tests "additional_flags=-maltivec" "auto"
Pedro> +    altivec_abi_tests " default ABI, auto:" "additional_flags=-maltivec" "auto"

It would be both prettier and better encapsulation if with_test_prefix
supplied the space.

I love the comment.
