I am not sure if I understand what you mean by "skipped".
Consider the following file in outline-mode:
-----
<point>
* This
word word
-----
I tried the following command with M-:
(progn
(visible-mode -1)
(search-forward "word")
(message "1:: current-column = %d" (current-column))
(redisplay)
(message "2:: current-column = %d" (current-column))
(indent-to 50)
(message "3:: current-column = %d" (current-column))
(redisplay)
(message "4:: current-column = %d" (current-column))
(visible-mode +1)
(message "5:: current-column = %d" (current-column))
(redisplay)
(message "6:: current-column = %d" (current-column))
(visible-mode -1))
First, I left the heading unfolded:
1:: current-column = 4
2:: current-column = 4
3:: current-column = 50
4:: current-column = 50
5:: current-column = 50
6:: current-column = 50
Then, I undid the indent, folded the heading, and repeated
1:: current-column = 4 <==== same despite text being invisible via overlay
2:: current-column = 4
3:: current-column = 50
4:: current-column = 50
5:: current-column = 50
6:: current-column = 50
Then, I undid the indent again, and applied 'invisible text property to
the heading text
1:: current-column = 0 <==== now, `current-column' ignores the invisible text
2:: current-column = 0
3:: current-column = 50 <=== This presumably inserts more tabs/spaces, but not!
4:: current-column = 0 <=== redisplay changed `current-column' ??
5:: current-column = 50 <=== indeed, the number of spaces is the same as visible text
6:: current-column = 50
Then, I repeated again, but applied 'rear-nonsticky (invisible) text
property as well
1:: current-column = 0
2:: current-column = 0
3:: current-column = 50
4:: current-column = 50
5:: current-column = 50
6:: current-column = 50
I cannot make much sense of the above results.
