It's one of those cases where it's funny it hasn't been noticed before,
since the effects won't be confined to libdraw. Anyway, that change seems
ok,
although it's really a particular type of conflict (between set R29 and use
R6 which depends on R29),
but expressing that is tricky with the limited value tracking there, and
the ADD R29 makes
as good a use of the delay slot as any.
