Hi!
Below is a small documentation patch. Unfortunately, I had not enough
time to compile 1.3.129 (it takes hours on my machine); so the patch
is untested.
Greetings,
Juergen

+A @emph{custos} (plural: @emph{custodes}; latin word for "guard") is a
+staff context symbol that appears at the end of a staff line. It
+anticipates the pitch of the first note(s) of the following line and
+thus helps the player or singer to manage line breaks during
+performance, thus enhancing readability of a score.
+
+@quotation
+@lilypond[verbatim]
+
+\score {
+ \notes { c'1 d' e' d' \break c' d' e' d' }
+ \paper {
+ \translator {

+ Custos \override #'style = #'mensural;

+
+Custodes were frequently used in music notation until the 16th century.
+There were different appearences for different notation styles.
+Nowadays, they have survived only in special forms of musical notation
+such as via the editio vaticana dating back to the beginning of the 20th
+century.
+
+For typesetting custodes, just put a @code{Custos_engraver} into the
+@code{StaffContext} when declaring the @code{\paper} block. In this
+block, you can also globally control the appearance of the custos symbol
+by setting the custos @code{style} property. Currently supported styles
+are @code{vaticana}, @code{medicaea}, @code{hufnagel} and
+@code{mensural}.
+
+@quotation
+\paper {
+ \translator {
+ \StaffContext
+ \consists Custos_engraver;
+ Custos \override #'style = #'mensural;
+ }
+}
+@end quotation
+
+The property can also be set locally, for example in a @code{\notes}
+block:
+
+@quotation
+\notes {
+ \property Staff.Custos \override #'style = #'vaticana
+ c'1 d' e' d' \break c' d' e' d'
