As far as I can understand, a \hspace #0 gives a markup that is
0pt wide but has a height that is the total height (i.e. the depth + the
height) of the characters in the font. That's the only way I can explain
what happens in your example. However, I'm not sure if that's a good
behaviour for \null in general. Consider for example the difference
between the two boxes in
\markup{\box \column { A \line {a \hspace #0.0 } }
\box \column { A \line {a \null} } }
I think the current implementation of \null behaves more intuitively.
On the other hand, the alignment issues of markups in general are far
from clear.

Could \null mimic the behavior of \hspace #0 ? It would be nice if we
could use it in the following way:
\layout{ raggedright=##t}
{ \fatText
c4^\markup{ \null aaa}
c4^\markup{ \null qqq}
c4^\markup{ \hspace #0 aaa}
c4^\markup{ \hspace #0 qqq}
}
