A keyboard macro only records the keys you hit.  So, not only the above
will do something odd, but if you record a keyboard macro in your foo.el
buffer and then play it back in a Dired buffer ... better make backups first.

The problem with line-move-visual and keyboard macros, is that if you
record your macro on a piece of that text that fits just fine without
line-wrapping, and then play it somewhere where lines are wrapped, you
may find your macro doesn't do what you wanted any more.  In itself,
this is no big deal, but it's easy for people to forget (or to not know)
about this detail because line-movement has been "mostly logical" for
many years.
