(reftex-isearch-switch-to-next-file):

Use `find-file-noselect' instead of `find-file' (for Emacs 22 and 23).
(reftex-isearch-minor-mode): If `multi-isearch-next-buffer-function'
is bound set it to `reftex-isearch-switch-to-next-file'.  Otherwise,
set 4 obsolete variables for backward-compatibility with Emacs 22.
