 rectangle-mark-mode: Tabs + Inability to C-x r o a rect. of width 4

[Message part 1 (text/plain, inline)]

In the attached screenshot, I am trying to C-x r o a rect. of width 4.
The intention is to indent the whole snippet to column 4.

Now, if you move the cursor vertically down (and subsequently in the
horizontal direction), you will note that the highlighted region
"forcibly" becomes zero width or of 8 chars.

I can in no way rest the cursor at col. 4 (on a row that has the tabs)

Note that the buffer in whitespace mode suggest the presence of tabs.

		  '(hi-lock-mode eldoc-post-insert-mode outline-minor-mode))))

I assumed that when you went around like a petulant child and closed all
your bugs, that was you done. Not sure why now you are back and opening
more bugs, nor why anyone should invest time on them.

Glad we agree. Closing.

Not sure what this has to do with rectangle-mark-mode.  The same holds
in all Emacs versions so far.

Sure you can: C-a C-x C-x C-4 C-f.

But, yes, this is a limitation that is difficult to fix in the old
rectangle UI whereas the rectangle-mark-mode offers the possibility to
fix it more easily, at least from the UI point of view.
The implementation is still missing (tho cua-rect.el provides the
feature already).

This will be useful, if available.
