Maybe I'm missing something, but after reading (info "(emacs) Auto
Scrolling") and the docstrings of the variables
`scroll-up/down-aggressively', the behavior I observe after playing a
bit doesn't seem right to me.
Recipe from "emacs -Q":
1. Visit the attached file.
2. Adjust the height of the Emacs GUI frame so that only lines 1 to 11
are visible. With this setup it is easy to tell the relative position
of a line in the window in terms of percentage from the top or bottom,
since each line counts as 10% for such percentages.
3. Go to line 1.
4. Type: C-u 1 5 C-n
--> Point goes to line 16, and that line is centered in the window. So
everything is as expected so far.
5. M-: (setq scroll-up-aggressively 0.7) <RET>
6. Repeat steps #3 and #4.
--> This time I observe that point goes to line 16, but that line is
near the bottom of the window (9th line; 20% from the bottom) when it
should be near the top (4th line; 70% from the bottom).
I also observe a misbehavior when testing scroll-down-aggressively:
1. M-: (setq scroll-down-aggressively 0.7) <RET>
2. Go to line 30 and make that line the last visible one.
3. Type: C-u 1 1 C-p
--> I observe that point goes to line 19, but that line is the 10th in
the window (90% from the top), when it should be the 8th line (70%
from the top).
