That's what I had in mind - some construct which has the Help system add
a link to the custom group automatically (just like customization links
for options).

Many packages have a root group which should be sufficient for this
purpose.

I'm afraid this might be confusing.  But for a a minor mode like
`show-paren-mode' a clickable link from the command to its major
customization group (whose name is not easily deducible in this
particular case) should be mandatory.

Does `Man-width' trigger a refit when the window gets resized?

That would require substantial work.

Agreed.  We should also give the header line items the standard button
appearance so it's easy to see (1) which sorting method is currently
selected, (2) where and what I have to click, and (3) the position of
the handle for dragging.
