bug#9666: 24.0.50; C-d has unexpected behaviour in CUA rectangle mode

[Stefan Reichör]

Just activate cua mode, select an rectangle and hit DEL or C-d:
M-x cua-mode
C-RET
select rectangle
DEL

I expect this command to delete the whole rectangle

But it deletes only one character and deactivates the marked
rectangle

I see somewhat different behavior with the above recipe: DEL (backspace
key), deletes the one-column rectangle immediately following the
selected rectangle, and does not deactivate (unhighlight) the latter;
C-d, on the other hand, does delete the selected rectangle.  This is on
GNU Emacs 24.0.90.3 (i686-suse-linux-gnu, GTK+ Version 2.22.1) of
2011-10-04 on escher.

Digging further into this problem.
There are some modes that bind delete (not BS) to delete-forward-char (e.g. the
*scratch* buffer).
When this is the case the rectangle is not deleted.

When delete is bound to delete-char then the rectangle is deleted as expected.

Ah, I guess you also meant <delete> above, not DEL.  With <delete> I
also see what you reported.  This is indeed different from the behavior
of <delete> with an active (highlighted) region.

But the standard binding of delete-char is C-d, which you (meant to)
report above behaves like <delete> (assuming you meant that key instead
of DEL); see also your Subject header.  Whereas, as I said, I do get
deletion with C-d.  So the unexpected behavior in cua-mode is (just) with
<delete> (bound to delete-forward-char), is that what you're saying?  If
so, I agree (assuming, that is, that <delete> should behave the same
with rectangles in cua-mode and with active regions outside of cua-mode;
I don't know, since I haven't made much use of cua-mode).

I assumed that C-d and <delete> are bound to the same function.
I see that this is no longer the case - and this also the reason
for the different behaviour in cua rectangle mode.

I confirm that C-d does the expected thing. <delete> does not work as expected.

cua rectangle mode should treat delete-forward-char the same way as delete-char.

bug#9666: 24.0.50; C-d has unexpected behaviour in CUA rectangle mode

[Glenn Morris]

To summarize, cua-rect.el, and anything else that remaps delete-*
commands, may need updating for delete-forward-char now being bound to
[delete].

Done.
