Can you? I fail to get something like
\markup { x x x \hspace #-15 x x x }
to work, and actually this looks like a bottomless pit: on stencil
extents, interval-empty? is getting called a lot, including
the builtin ly:stencil-empty?, and those return true for stencils with a
right edge before the left edge.
It would appear that a whole lot is terribly broken with regard to
backspacing constructs as they are all being diagnosed as empty.
