Web doc anomaly

[David Bobroff]

Not sure if this is the right list for this post but here goes.  I was
just visiting:

http://lilypond.org/doc/v2.5/Documentation/user/out-www/lilypond/Gregorian-square-neumes-ligatures.html#Gregorian-square-neumes-ligatures

..and was surprised to see that the only neumes which were displayed as
neumes were three porrecti (porrectæ, porrectuses...).  All the others
were simply letters.
