 where `T` is quasi-upper-triangular and `Z` is orthogonal, both with the
 same element type as `A`.  This is what you get by invoking the above-mentioned
 functions with matrix arguments whose element type `T <: Real`.
-By default, the result is not quite in standard form, in that some
-pair-blocks (and therefore rank-2 invariant subspaces) are not fully resolved.
+By default, the result is in standard form, so

+(This differs from the original version in GenericLinearAlgebra.jl.)
 
-If the optional keyword `standardized` is set to `true` in `gschur`, a
-standard form is produced.  There are currently a few cases where this
-does not give a correct decomposition (a problem under study).

 Eigenvectors are not currently available for the "real Schur" forms.
