bug#6073: 23.1.50; delete-selection-mode

[Richard Stallman]

I found a reproducible test case for the painful result I mentioned
before with C-u C-y in Delete Selection mode.

This Emacs is somewhat old; I have not built a newer one.
I will try to do so soon.

I visit the text between the ---- lines (not including them)
in Fundamental mode, do M-x delete-selection-mode RET to enable it,
then I go to the blank line after the first paragraph and type
C-SPC C-u C-n M-w C-x C-x C-u C-y
and the text does not change.  Apparently C-u C-y deletes
the region before yanking.

  noncommercial activities as somehow commercial-like or treating them
  as if they were commercial.

* ACTA must not tighten digital handcuffs: it must not hinder any
  activity in regard to any product on account of its capacity to
  circumvent technical measures that restrict use of copies of works

You probably already know this, but in case you do not: C-x C-x activates the
region. Since it is active, your yank replaces the region text.

If you do C-g after C-x C-x I think you will get the behavior you expected.

Indeed.

Better is to use C-u C-x C-x, which contrary to C-x C-x doesn't activate
the region.

Yes, I know that is the explanation for what happened.
The point is, it was quite inconvenient.  And it surprised
me that C-y would delete the region.

This is apparently intended behaviour in Emacs 24, so I'm closing this
bug report.
