As promised, here is a version of w3m-decode-entity-string
that handles strings with multiple embedded entities without
creating a temporary buffer.
(defun w3m-decode-entity-string (encoded-str)
"Decode entities in the string STR."
(let (decoded-str (curr-pos 0) match-pos)
(setq match-pos (string-match w3m-entity-regexp encoded-str curr-pos))
(substring encoded-str curr-pos match-pos)
(match-string 1 encoded-str)
(setq curr-pos (match-end 0))
(setq match-pos (string-match w3m-entity-regexp encoded-str curr-pos))))
(concat decoded-str (substring encoded-str curr-pos (length encoded-str)))))
Here is the output of the function for several test cases:
ELISP> (w3m-decode-entity-string "&<>")
ELISP> (w3m-decode-entity-string " paul & jose <katsumi> ")
" paul & jose <katsumi> "
ELISP> (w3m-decode-entity-string "no entities")

I look forward to this enhancement.
My thanks to you, Katsumi, and the other emacs-w3m maintainers for
contributing such a useful package to the Emacs community.
