I noticed that `C-c ?' in HTML mode doesn't work as it is described in
the Emacs manual, and for a few of the tags that it supports. Some of
the tags lacked descriptions, notably DIV and SPAN. The patch below
tries to rectify both of these.
Here's the Emacs manual's description of `C-c ?':
`C-c ? TAG <RET>'
Display a description of the meaning of tag TAG (`sgml-tag-help').
If the argument TAG is empty, describe the tag at point.
Thanks for Emacs,

* textmodes/sgml-mode.el (sgml-tag-help): Prompt user for tag as
the documentation describes.
(html-tag-alist, html-tag-help): Add descriptions for undocumented
entries and make note of obsolete tags.
