The discussion led aside from the initial idea for \deadNote.
This is a command that works in every situation and is therefor
more user-friendly *and* it works with tablature, and this was the starting
point of it all.

When tablature features will be part of lilypond, I can just say

c4 \deadNote d e f | < c \deadNote e g>4

and the cross will be visible in normal and in tablature staves.
Of course this can be done with tweaking and overriding, but as Graham
pointed out in a message some months ago, it would be the best if no scheme
hacks will be necessary for standard notation (and dead notes are
kind of standard in pop and rock music on guitar and bass).

It is not that long ago that \override and \tweak were the reason for me
not to use lilypond for my projects (ok, now I'm a bit more scheme-savvy,
but this is another story).

<e \xHead a c>
