I personally think that this property-init.ly file isn't something you
just expect a user to find. I once did a whole document to explain the
macros in that file, but after finishing -- and going over it -- I
realized it was completely ridiculous to expect someone to find it,
and then perhaps go through it.

Obviously, the property changes should be on the concerned pages,
while putting a strong emphasis on the fact that there are two
different commands for the two different type of slurs.

I think it would genuinely be effective to document \tieUp, etc. in:
http://lilypond.org/stable/Documentation/user/out-www/lilypond/Ties.html#Ties

Perhaps each time, there could be, in addition, a link to a more
general section documenting the entire file (somebody who's looking
for a way to orient ties, then stumbles on the whole thing -- and is
prepared when he decided to orient stems).

Graham, I'll volunteer on this one *if* you want.
