Unless you are at the beginning of a line, rehearsal marks (i.e. texts 
typeset
using \mark) are by default center aligned over bar lines. If you want to
change that alignment, use a setting like

\override Score.RehearsalMark #'self-alignment-X = #LEFT

The placement after line breaks is a bit special and is handled by the
function pointed to by the after-line-breaking property of the RehersalMark
object, which by default moves the mark 3.5 steps to the right, relative 
to the
left end of the stave.
