This is not what I get with Info-breadcrumbs-depth = 4.  Instead, I see
the full line like below:

> With a value of 5, you get this instead:

Now I incremented the default value to 4, so with the maximal depth of 4
actually there is no eliding now by default.  In my tests, the length
of the breadcrumbs line rarely approaches 80 columns.  However, if this
will cause a real problem then maybe instead of the number of nodes
Info-breadcrumbs-depth should specify the maximal length of the breadcrumbs
line measured in characters (this is easy to calculate).

OK, now removed the initial `> '.
