questionable unfold-repeats for tremolo

[Michael Welsh Duggan]

The unfold-all-repeats.ly example in Tips and Tricks demonstrates the
unfolding of a tremolo, specifically \repeat tremolo 8 {c'32 e' }.
This should expand to 8 sets of 32nd-note pairs, I would think.
However, in the output, it shows 8 sets of 16th-note pairs.  I think
this is a bug, but am prepared to accept that I have misunderstood
the syntax.

Examples from versions 2.1.35, 2.0.3, and 1.8.2 exhibit this behavior,
which is why I am extremely uncertain as to whether I am correct about
this.
