[Octave-bug-tracker] [bug #65330] dblist should print out lines around current point in the stack, not just bottom of stack

[Rik]

Follow-up Comment #5, bug#65330 (group octave):

I tested with dblist.  It seems to work well unless there is an error, in
which case line numbering gets reset.  However, a subsequent dbnext will
re-initialize the line in the file and then dblist goes back to working
correctly.  See the attached sequence which uses 'ls' with a non-existent file
to throw an error.
