The repeated music is fully written out, as many times as
-specified by @var{repeatcount}. This is useful when
+specified by @code{@var{repeatcount}}. This is useful when
entering repetitious music.

If there are more repeats than there are alternate endings, the earliest
repeats are given the first alternative.
A single repeat with one alternate ending:
@lilypond[verbatim,quote,relative=2]
-\repeat volta 2 { c4 d e f }
+\repeat volta 2 { c4 d e f | }
\alternative {
- { c2 e }
- { f2 g }

A single repeat with more than one alternate ending:
@lilypond[verbatim,quote,relative=2]
-\repeat volta 4 { c4 d e f }
+\repeat volta 4 { c4 d e f | }
\alternative {
- { c2 e }
- { f2 g }

Multiple repeats with more than one alternate ending:

If a repeat starts in the middle of a measure and has no alternate
endings, normally the end of the repeat will also fall in the
middle of a measure, so that the two ends add up to one complete

-Only three kinds of percent repeats are supported: a single slash
-representing a single beat (regardless of the duration of the repeated
-notes); a single slash with dots representing one full measure; and
-two slashes with dots crossing a bar line representing two full
-measures. Neither multiple slashes representing single beat repeats
-consisting of sixteenth or shorter notes, nor two slashes with dots
-representing single beat repeats consisting of notes of varying
-durations, are supported.
