I am not quite sure why it isn't working, but I verified it on my  
machine.  However, it seems that it works for other functions.  Try  
running:

octave:1> s = dbstop('isequal',1)
s =  27
octave:2> zz = dbstatus
zz =
{
  name = isequal
  file = /sw/opt/octave/hg20080331/share/octave/3.0.0+/m/general/ 
isequal.m
  line =  27
}

octave:3> a=1;b=2; isequal(a,b)
isequal: line 27, column 7
nargin
keyboard: stopped in /sw/opt/octave/hg20080331/share/octave/3.0.0+/m/ 
general/isequal.m at line 27
debug>

So, I'm not quite sure why it can't seem to hit the breakpoint in  
test_func, despite it showing up as being set.
octave:1> s = dbstop('test_func',2)
s =  2
octave:2> zz = dbstatus
zz =
{
  name = test_func
  file = /Users/jpswensen/src/test_func.m
  line =  2
}

Since only the functions are stored in bp_table, then the list of  
breakpoints is retrieved from octave every time.  So I think that if  
the dbstatus returns a value for a breakpoint it should be there.
