Hmm.  I'm not sure why we aren't just using

  tilde_expand ("~/.octaverc")

so I changed it to that.

OK, I made this change.

I added these functions to scripts/path.

I think we should have a "setpath" function and have savepath write

  setpath ("...")

instead of

  LOADPATH = "..."

so that saving and loading the path will continue to work properly
after we eliminate built-in variables.  I made this change to
savepath.m and created a simple setpath.m file.

Thanks,

jwe
