Comments in dget38.f look wrong. (only cosmetic ones)

Description

• DGEHRD reduces a general matrix A to upper Hessenberg form
• DHSEQR computes eigenvalues of a matrix of Hessenberg form and the Schur form

but in dget38.f, comments are only "Compute Schur form" --- lapack-3.9.1/TESTING/EIG/dget38. 2021-03-26 03:25:15.000000000 +0900 +++ lapack-3.9.1/TESTING/EIG/dget38.f 2021-06-21 15:51:04.000000000 +0900 @@ -194,7 +194,7 @@ $ VMUL = ONE CALL DLACPY( 'F', N, N, T, LDT, TSAV, LDT ) - Compute Schur form + Compute upper Hessenberg form of matrix CALL DGEHRD( N, 1, N, T, LDT, WORK( 1 ), WORK( N+1 ), LWORK-N, $ INFO ) @@ -210,7 +210,7 @@ CALL DORGHR( N, 1, N, Q, LDT, WORK( 1 ), WORK( N+1 ), LWORK-N, $ INFO ) - Compute Schur form + Compute eigenvalues and the Schur form T CALL DHSEQR( 'S', 'V', N, 1, N, T, LDT, WR, WI, Q, LDT, WORK, $ LWORK, INFO )

Checklist

• [x] I've included a minimal example to reproduce the issue
• [x] I'd be willing to make a PR to solve this issue

Yes. OK. (1) Please submit a PR. (2) Can you check as well for s, c, and z arithmetic then? (3) "Compute upper Hessenberg form of matrix" is fine. We could also write: "Reduce to upper Hessenberg form". Either way is fine. Cheers, Julien.
