Well, this decision was made long before I was around here, no clue whether
you may find some reasoning in the archives.
Though, here some illustrating code:
\new Staff {
\override PercentRepeat.color = #red
\override DoublePercentRepeat.color = #yellow
\override RepeatSlash.color = #cyan
\override DoubleRepeatSlash.color = #green
<>^"PercentRepeat, red"
\repeat percent 2 { c'1 }
\break
<>^"DoublePercentRepeat, yellow"
\repeat percent 2 { d'1 e' }
\break
<>^"RepeatSlash, cyan"
\repeat percent 4 { c'16 c' c' c' }
\break
<>^"DoubleRepeatSlash, green"
\repeat percent 4 { c'8. c'16 }
}
If we look closer at the grobs we may guess some thoughts why they are
separated:
PercentRepeat is a spanner (and needs to be one), the others not. Every
grob is an item _or_ a spanner, never both.
(So no chance to merge PercentRepeat with the others.)
DoublePercentRepeat is _not_ a rhythmic grob, and can't be one.
(So no chance to merge DoublePercentRepeat with DoubleRepeatSlash and
RepeatSlash.
Not sure about RepeatSlash and DoubleRepeatSlash, though.
Also, I have no clue why DoubleRepeatSlash supports the
outside-staff-interface, but RepeatSlash not.
Cheers,
Harm
