defconst I think. The value is not supposed to be changed.

Users are indeed not supposed to change defvar unless they know what
they are doing. But it is not considered private - there is a guarantee
that the meaning or type of the variable is not going to change.

Yes. Having "--" means - if you use this variable, do it at your own
risk; we can re-purpose it or change or rename or do whatever at any
time.

Do I understand correctly that the above will simply affect debug output
when maxima references where a problematic line is located in the source?

May empty lines be intentional in some maxima code?
