hmmm, it does appear that restoredefaultpath() isn't working as I had thought 
it would.

I have 3.6.0-rc1 installed and when I run via ./run-octave ...

p1 = path ();
path ("");
restoredefaultpath ();
p2 = path ();
c1 = strsplit (p1, pathsep);
c2 = strsplit (p2, pathsep);

setdiff (c1, c2)

Notice both p1 and p2 include the path info for the archives m-files. p1 
includes the paths added in ~./octaverc, and p2 includes the paths to the 
installed m-files.
