I can reproduce the issue if the last line that I still see in the buffer (when point is at the beginning of the buffer) is the line containing "false." in the definition of declarative_false/0, i.e., line 28 in the file. We now define a keyboard macro that is supposed to remove the 8 spaces that indent all code snippets that appear within the 4 
 blocks.

With point at the beginning of the buffer, please press C-x ( to start
recording, and then press the following keys:

     C-s 
 block is unexpectedly
changed to:

    





                ).
    


whereas the expected result it:

    
mi2_safe(g(G)) :-
        (   safe_goal(G) ->
            mi_clause(G, Body),
            mi2_safe(Body)
        ;   throw(cannot_execute(G))
        ).
    



However, if I revert all changes and simply enlarge the frame, or try
the exact same sequence after removing the filler text between lines 33
and 52, or try the macro on the fourth snippet while the 
 block is
completely in view, everything works exactly as expected.

Thus, implicit scrolling and the frame size may unexpectedly interact
with this keyboard macro.

This is related to the C-n behavior when executing macros, the same
problem which causes bug#23551 and #13452.  If you set
line-move-visual to nil in the buffer where you run the macro, the
problem disappears.

Thanks.
