(sgml-value): Don't perform the skeleton-transformation

on the value.

(sgml-transformation): New variable.
(sgml-mode-common): Use it.
(html-href-anchor): Ask for address, wrap around text.
(html-name-anchor): Same as above, without initial input.
(html-image): No initial input for address.
(html-ordered-list): Incorporate char into string.
(html-unordered-list): Same as above.
(html-checkboxes, html-radio-buttons): Rewritten.

(sgml-char-names): Change ensp to nbsp.

(sgml-tag): Use intangible here.
(sgml-tags-invisible): Don't add intangible property
separately here.  Just the category property is enough.
Eliminate local variable `point'.
Bind inhibit-point-motion-hooks.
