I'm not aware of this (though I don't doubt that you're right).
Could you give me an example?

It works in the context of a `concat', so I think the problem is some
kind of interaction with `word-space'.

This file illustrates it:

\version "2.13.4"

%% Here the negative hspace works just as expected.
\markup {
  \column {
    \concat { I I I }
    \concat { I \hspace #0.9 I I }
    \concat { I \hspace #-0.9 I I }
  }
}

%% But the negative hspace here has very little effect.
\markup {
  \column {
    \line { I I I }
    \line { I \hspace #0.9 I I }
    \line { I \hspace #-0.9 I I }
  }
}
