I'm using MiKTeX and I can't confirm the latter. However I think I've
narrowed it down a little. With a testfile containing the lines
\beginR\centerline{1}\endR
$\centerline{2}$
I get this output with \tracingoutput=1 running normal eTeX 2.2 (same
result with pdfetex).

Judging from this, the contents of both lines should be centered but the
former is in fact *not* in the output. My guess is that something goes
wrong in the module <Handle a glue node for mixed...>, but I can't say for
certain, as I don't speak Pascal very well.
Cheers,
