I'm afraid it did not, which puzzles me in view of the confidence you
expressed. I wonder if we did something different again. I did emacs
-Q, evalled line-move-finish and line-move-to-column with your patch
applied and evalled the sexps in your test file lmii.txt. Here are the
results I got:
1.
i. with '(invisible t):
fl-1
Starting with point on or after the `l' of `line7', cursor moves
to the `l' of line6, then the `l' of line4, then the `l' of line2,
then the `l' of line1.
C-p
a. Starting with point on or after the `i' of `line7', cursor moves
successively to the corresponding column of the preceding line.
b. Starting with point on the `l' of `line7', cursor moves to the `l'
of line6, then the `l' of line4, then the `l' of line2, then the
`l' of line1.
ii. with '(invisible t rear-nonsticky t):
fl-1
Starting with point on or after the `l' of `line7', cursor moves
successively to the `l' of the preceding line.
C-p
Starting with point on the `l' of `line7', cursor moves
successively to the corresponding column of the preceding line.
I also tested making line4 invisible (add-text-properties 19 25 ...),
which one of the original bug reports was about:
2.
i. with '(invisible t):
fl-1
Starting with point with point anywhere on line7, cursor moves
successively to the `l' of the preceding line.
C-p
Starting with point anywhere on line7, cursor moves to the
corresponding column of line6, then to the corresponding
column of line5, then to the `l' of line5, then back to the
goal column in line3 and likewise with line2 and line1.
C-n
Starting with point anywhere on line1 or line2, cursor moves to the
corresponding column of the next line. Continuing from line3, C-n
move cursor to the `l' of line5, and with the next C-n to the
previous goal column in line5. Subsequent C-n's move the cursor to
the next line also at the same column.
ii. with '(invisible t rear-nonsticky t):
fl-1
Starting with point with point anywhere on line7, cursor moves
to the `l' of line6, then to the `l' of line5, then to the end of
line3, then to the `l' of line2 and likewise line1.
C-p
Starting with point anywhere on line7, cursor moves to the
corresponding column of line6, then to the corresponding column of
line5, then to the `l' of line5, then to the end of line3, then
back to the goal column in line2 and likewise in line1.
C-n
a. Starting with point on the `l' of line1, line2, or line3, cursor
moves to the `l' of the next line. Continuing with C-n at
line3, cursor moves to the `i' of line5, then to the `l' of
line6 and likewise line7. However, if, after reaching the `i'
line5 with C-n, I then type C-p, cursor moves first to the `l'
of line5, then to the `l' of line3 (not, as above, to the end of
line2), and to the `l' of line2 and line1.
b. Starting with point on any position but the `l' of line1 or
line2, cursor moves to the corresponding column of the next
line. Continuing from line3, cursor moves to the `l' of line5,
then to the original goal column in line5 and likewise in line6
and line7.
