Specified spaces are very convenient for displaying tabulated lists, and the buffer-invisibility-spec is supposed to be particularly useful for displaying database records, but in practice these two don't work together. It would be great if they did.

A "replacing" display property in effect forces the display engine to ignore the entire chunk of text "covered" by that display property, so the fact that this chunk of text is in this case invisible is never seen, nor acted upon. Once the display engine is done producing the stretch of white space for the display property, it jumps to the end of the text "covered" by the property, and continues from there.

Consider the following program:
(with-current-buffer (get-buffer-create "*spaces*")
(erase-buffer)
(let ((indent (propertize " " 'display '(space :width 3))))
(put-text-property (point) (progn (insert indent "r1\n") (point)) 'invisible 'a)
(put-text-property (point) (progn (insert indent "r2\n") (point)) 'invisible 'b))
(add-to-invisibility-spec 'a)
(pop-to-buffer (current-buffer)))
The first record (r1) is hidden, but not the indentation that precedes it; so, instead of looking like this:
r2
The buffer looks like this:
r2
(This is because the invisible property doesn't apply to the display spec.)
It's easy to fix when the replacing display spec is a string (by putting the same invisibility spec on the string), but there doesn't seem to be a way to add an 'invisible property to the specified space.
