In ?qr (and probably in ?svd), \bold is inside \eqn{}, so it is being
interpreted as LaTeX markup rather than Rd markup, and since no
alternative was given, is displayed as-is.
If you actually wanted it to display properly in HTML and ascii, the
current \eqn{\bold{Ax} = \bold{b}} would have to be written as something
like
\ifelse{latex}{\eqn{\bold{Ax} = \bold{b}}}{\bold{Ax} = \bold{b}}
which is pretty tedious to write, and it's not the only example on that
page. So I doubt if anyone will fix it.

You missed the part about \eqn.
