This is not my error, it's lilypond's error.  Additionally, the point
is not that it's possible to manually fix the problem.  It's possible
to manually fix all placement problems.

If the problem is that it's too hard to figure out stem direction
automatically, that's one thing. "Hard to fix" is not a reason to not
file a bug, but it might influence my motivation to go try and fix it
myself.  If the problem is that there's a policy of basing stem
direction only on pitch and not potential collisions, that's another
thing, and would be an interesting thing to talk about.

C'mon guys, there's no need to be defensive.  What other software does
and how much it costs is not relevant.

Well, it's not possible in general to get all layout perfect from a
human's point of view.  But the closer to the ideal the better.

Perhaps not, but that's not a reason to not file a bug, and not a
reason to not look into a fix, though it might be a reason to
eventually give up on a fix.

Although your example looks fine to me, since nothing is actually
colliding with anything else.
