You mean 'ambitus', 'staff-bar' and so on? They are defined by the
property 'break-align-symbol' for the respective layout objects.
For example, the 'break-align-symbol' property for the object Ambitus
is 'ambitus'. See also the second link I provided in the previous
answer.

The value is a Scheme list. However, if you just look at a few examples,
it's easy to grasp the pattern.

I just copied the default value of the list and changed the
spacing to next-note. The list covers a number of cases that
often appear in normal score, i.e. that a clef is follow by a
key signature or a time signature or a bar line or ...
Of course, if you know that one of these cases never will happen
in your score, then there's no need to include it.

'alist' is short for association list, which is a common concept in
LISP related languages like Scheme. For comments, just use the
comment syntax of Scheme, i.e.

\override Staff.Clef #'space-alist = #'(
        ; Copy of the default values:
        (ambitus extra-space . 2.0)
        (staff-bar extra-space . 0.7)
        (key-cancellation minimum-space . 4.0)
        (key-signature minimum-space . 4.0)
        (time-signature minimum-space . 4.2)
        (first-note minimum-fixed-space . 5.0)
        ; Changed the default value 0.5 to 1.5:
        (next-note extra-space . 1.5)
        (right-edge extra-space . 0.5))

See the Scheme tutorial in the manual with its link to other Scheme
documention for more information.
