Some more information after a bit of debugging with `edebug-defun':
the problem is in the `reftex-format-special' function.

    (reftex-format-special "fig:bar" "~\\ref{%s}" "\\pageref")

returns the expected

    "~\\pageref{fig:bar}"

while

    (reftex-format-special "eq:foo" "~\\eqref{%s}" "\\pageref")

returns

    "~\\eqref{eq:foo}"

but I would expect

    "~\\pageref{eq:foo}"

The docstring of `reftex-format-special' says

    Apply selected reference style to format FMT and add LABEL.
    Replace any occurrences of "\ref" with REFSTYLE.

Should we replace any occurrences of "\[a-zA-Z]*ref*" with REFSTYLE
(or something like this that will work with `\eqref')?  It's not clear
to me why there is a `while' loop.
