Details:

When running in debug mode, Octave does not update the current line number,
although it does update the current file.

If line 100 of file1.m  is "keyboard", and the user runs file2.m which causes
an error, it will report the error as "file2.m, line 100".

This was done so that the stack frame in the original file doesn't get the
wrong line number inserted.  (See comment near line 700 in
libinterp/parse-tree/pt-eval.cc)

The attached patch keeps track of when a new stack frame is created to run
user code, and tracks the line numbers in that new frame, even if it is debug
mode.
