Subject: bug#64696: 30.0.50; indent-to inherits preceding text properties, including 'invisible

Hi,

This is a follow-up of Org mode bug report
https://orgmode.org/list/8b691a7f-6b62-d573-e5a8-80fac3dc9bc6 <at> vodafonemail.de

Consider the following MWE:

(progn
  (switch-to-buffer (get-buffer-create "*Test*"))
  (erase-buffer)
  (insert "Test case with char before point hidden<point>     :more text:")
  (search-backward ">")
  (forward-char)
  (with-silent-modifications (put-text-property (1- (point)) (point) 'invisible t))
  (let ((indent-tabs-mode nil)) (indent-to 100)))

The text is inserted and then indented as expected when 'invisible
property is not applied:

-------------
Test case with char before point hidden<point>                                                      <point>     :more text:
-------------

However, after un-commenting `put-text-property' line, no indentation is
done "visually" because Finsert_char is called with INHERIT argument Qt.
