What hasn't been answered?  If by original question you mean

  Without adding the 'bar' directory to LOADPATH, since I need the bar
  directory only once, is there a way to specify to octave where to
  look for mstuff.m just one time?

Then I think the answer is to use source().  If the file may be in any
one of a number of directories (but none are listed in your LOADPATH)
and you just want to source the first one that is found, then
something like

  source (file_in_path (FILE))

should do it.  If file is called "foo.m", you have to say that.  Just
using "foo" won't work, because source() doesn't append ".m".

If you don't have a file called "./src1", then that looks right so

|   octave:1> source("./scr1.m")
|   octave:2> scr1
|   octave:3> eight
|   eight = 8

It's not clear to me that the source command failed.  To be sure, you
need to check to see if the variable `eight' exists after the call to
source, I think.
