marks, voltas, and key signatures

[Anthony W. Youngman]

Various problems I want to fix ...

Marks - I want to put some text on a barline. I thought it was "\mark 
\markup", but that centres the text over the barline - no use when it's 
a long text :-( I want the text to start over the bar, not centred. How 
do I left-justify a mark, or what else should I do?

Voltas - is this a bug? They're floating way too high over the staff. An 
"x time bar" to me should be sitting almost touching the staff. But 
there's a gap the same height as the volta between it and the staff. AS 
I say, is this a bug, or how do I move the volta down?

And key signatures. I'm not used to seeing accidentals cancelled then 
reset. If I go from, say, three flats to four, lilypond gives me SEVEN 
accidentals, three naturals and four flats. To me it should be just four 
flats. Likewise, going from four flats to three, I would expect the key 
signature to be one accidental followed by three flats. How do I get 
this behaviour?

Cheers,
Wol

good idea to burden them with too much input. Hex always thought of his reports
