As far as I can understand, a \hspace #0 gives a markup that is

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.
There is a \strut command to do this, but last time I looked it was
broken.
\strut certainly doesn't appear to do anything now. What is is supposed
to do? If it's the same thing as \hspace #0 or #1, then wouldn't it
just be
(def-markup-command (strut layout props amount) (number?)
(if (> amount 0)
(ly:make-stencil "" (cons 0 0) '(-1 . 1))
(ly:make-stencil "" (cons 0 0) '(-1 . 1))))
(tweaked hspace)
... hey, how does hspace #0 do anything? if amount=0, then surely
\hspace shouldn't do anything?
(if (> amount 0)
(ly:make-stencil "" (cons 0 amount) '(-1 . 1))
(ly:make-stencil "" (cons amount amount) '(-1 . 1))))
