bug#3875: 23.1.50; buffer-substring does not copy the 'invisible property

bug#3875: 23.1.50; buffer-substring does not copy the 'invisible property

[Lennart Borgman]

A simple test in for example an org-mode buffer shows this. The doc
string says it should copy the properties.

How do I get a buffer substring with the text property 'invisible too?
Do I have to search them in the buffer and apply them to the string?
In that case should not Emacs have a function to do this?

Actually it looks like next-property-change etc also forgets `invisible'.

That seems highly unlikely.  Please post a recipe.

You are right. I was confusing next-property-change and
next-char-property-change.

Org mode uses overlays to make body parts invisible. So these is not
the bug I am hunting. Please close this.
