Note however that *mathematically* the above is entirely correct. It just uses 'q' instead of 'p', but as you know, in math you are allowed to use whatever letters you want..... as long as they are used consistently within one context. As the 'Usage:' and 'Arguments:' parts are "R-codish", using R object names, rather than mathematical notation, they are "out of context" from the math formula point of view ;-) .. I have changed that part to use 'p' now, ... but for R-devel only, as indeed, it's *not* a bug fix.

How exactly are you looking at that help page? Is it the HTML version or the text version? In any case, I'd guess that this is problem specific to your platform, but maybe reproducible by others, if you'd give the details...
HTML in R 2.10.1, I believe, see the NEWS item for 2.10.1 patched:
o Although \eqn{} in Rd files is defined as a 'verbatim' macro,
many packages expected \dots and \ldots to be interpreted
there (as was the case in R < 2.10.0), so this is now done
(using an ellipsis in HTML rendering).
(and another change fixes up misuse of \lambda).
