Re: multiple queries to delete excess backup version w/ custom

[Richard Stallman]

    "C-h k" followed by a click on that button shows documentation for
    widget-button-click -- not very helpful.  C-h k RET with point on the
    button just shows docs for Custom-newline -- also not very helpful.

It would be useful to enhance C-h k to get the documentation of what
a specific button does.  Would someone like to do that?
