There are more places where links leading to other customization buffers
are displayed as buttons: custom-browse-group-tag, custom-browse-variable-tag,
custom-browse-face-tag. The patch below changes their parent widget
from `push-button' to `custom-group-link', and adds corresponding
`button-face' and `mouse-face' to the widget `custom-group-link'.
This makes unnecessary explicit adding of `button-face' and `mouse-face'
to every instance of the `custom-group-link' widget. Also there is
a special customization widget for info links, so the patch replaces
`info-link' with `custom-manual' which makes unnecessary adding of
`button-face' and `mouse-face' as well.
I also noticed that a new face `custom-link' was recently added
to cus-edit.el. Currently it is a copy of `info-xref' and it
even retains its docstring and the group name `:group 'info'.
This is wrong. I've added a new face `link' to share for `custom-link',
`info-xref', and perhaps more faces could inherit from it.
Also the face `custom-button-unraised' uses the copy of `info-xref'.
But instead of inheriting from the new face `link', I think it's
better to use underline to distinguish unraised buttons from links.
The following patch also removes square brackets from links even
in customization buffers with unraised buttons, because the link face
makes square brackets unnecessary for links.
