* bug#27974: 25.2; string-rectangle on-the-fly preview bad

The command C-x r t string-rectangle in version 24 and previously
would "Replace rectangle contents with STRING on each line
(‘string-rectangle’)."  The same happens in version 25 but
differently.  In version 25 the change is displayed incrementally
character by character as you type as a dynamic preview.  With a large
displayed rectangle this can cause a lot of dynamic "flicker" as every
character on the display is moved.  This is driving me crazy.

I raised this issue on help-gnu-emacs.  I and at least one other person
thinks this preview feature should be optional even if it is the
default.  I think it is a pretty radical change however and would wish
it were not the default.  But at the least it needs to be possible to
disable the dynamic preview.  I really hate this feature.

Thanks,
Bob

P.S. The NEWS file says:

*** 'string-rectangle' provides on-the-fly preview of the result.

It is optional.

tags 27974 + patch
thanks

Filing this ticket generated more discussion and I was informed that
rectangle-preview variable controls this feature.  Yes!  This is what
I needed to know.  I really must ask, is this really a good change?
It is extremely annoying behavior.

    ;; Disable nasty on-the-fly preview from string-rectangle.
    (setq rectangle-preview nil)

However this bug ticket is still relevant because this information
should be provided in the NEWS (and perhaps Antinews) pages.

Let me suggest the following addition to the NEWS file.

 *** 'string-rectangle' provides on-the-fly preview of the result.
+This is controlled by the rectangle-preview variable.  Defaults to t.
+Set (setq rectangle-preview nil) if you want the previous behavior.

Please consider this patch.  Thanks.

Bob

I think it should also be documented in the docstring of
string-rectangle:

Can you reword this to make less use of passive tense?

Thanks.

Hmm, yeah, I'm not quite satisfied with the wording.  How about this:

When called interactively and option `rectangle-preview' is
non-nil, display the result as the user enters the string into
the minibuffer.
