Its not that controversial as remove in CVS just means move to the Attic
directory: nothing is lost and it can always be recovered, if necessary.

I never intended to leave things broken.  You have asked me to fix the
failures, and I will, but I'm not sure if that means submit further patches to
the mailing list or commit appropriate fixes.  Based on Mark Kettenis' e-mail,
I attach a simple fix for mi-var-child.exp.  Does it work in your case?  I
also suggested removing the duplicate test for in mi-var-display.exp (which
presumably existed before mi-var-child.exp was created).  Can I commit these
changes?
