To give an example: I have the following in my .emacs (simplified):

(create-fontset-from-fontset-spec "\
-b&h-lucidatypewriter-medium-r-*-*-*-100-*-*-*-*-fontset-egoge,\
mule-unicode-0100-24ff:-*-fixed-medium-r-*-*-*-120-*-*-*-*-iso10646-1")

Now, if I'd do `M-x custimize-fontset RET fontset-egoge RET', I'd
expect to see something like this:


Family: [b&h-lucidatypwriter                                      ]

[INS] [DEL] Charset:  [mule-unicode-0100-24ff                     ]
            Family:   [fixed-medium                               ]
            Registry: [iso10646-1
[INS]


But if we create this widget based on `fontset-info', I'd see a list
of dozens of charsets and character ranges. Have a look at it with 
`M-x describe-fontset RET fontset-egoge RET'.

I'd say that this would be surprising, if not confusing for users
that are not familiar with Emacs' concepts of charsets and
fontsets.
