'R' does not repeat single-selected note outside of note entry (range-selected only)

1. Open a score
2. Click a note
3. Press 'r'
Expected: the note is repeated directly after
Actual: nothing

Compare: still outside of note entry, select a whole chord, 'r' DOES repeat the whole chord. This is why the expected result is such, despite being outside of note entry. It seems it either should work for both or shouldn't for both.
Note: IF the note is the only note at the moment in the staff, shift-click on the note to select it with a blue box around it, then 'r' will repeat the note. However, it seems that should be unnecessary.
Also note: There is no way to use 'r' to repeat a single note within a chord outside of note entry mode, and there appears to be no way either in or out of note entry mode to repeat part (say, 2 out of 3 notes) of a chord (due to there being no way to select only part of a chord).

(0.9.6.3 and R. 3727 on Mac 10.6.5) (apologies if something like this is already there... searching for this is difficult, as 'repeat' has more than one context...)
