Now I see! There is a difference between
\unfoldRepeats {\repeat tremolo 4 c8 } % Works correctly
\unfoldRepeats {\repeat tremolo 4 { c8 } } % Gives 16th notes!!!

As long as we don't use \unfoldRepeats, both syntax forms provide the same

In version 2.8 and earlier, we used to have warning message
"warning: expect 2 elements for chord tremolo, found 1"
but it seems that this warning was removed in the revision

Still, the function unfold-repeats in scm/music-functions.scm only checks if the
argument is a SequentialMusic or an EventChord, which is too simplistic if
the ordinary engraver doesn't distinguish between the two cases.

If you want a single note with tremolo lines, then you should
use the
c1:32 syntax
whereas \repeat tremolo should be used for tremolo chords,
i.e. for constructs of the form
\repeat "tremolo" 4 { c'8 d' }

no, not completely accurate. IIRC,

\repeat "tremolo" 4 <NOTE>

is also supposed to work.
