What is the default value for listindent?

[David Bovill]

I'm trying to script around and inconsistency with the formattedwidth with
fields containing the new bulleted lists. For that I need to work out by
hand how far a line is indented by multiplying the listindent with the
listdepth. However when the listindent is not explicitly se it seems to
default to some unseemly large value - anyone know what this value is?
