Most of the changes could be handled by setting
the appropriate variables in your .octaverc, but
it would be nicer with system dependent defaults.

Maybe we could query the registry on startup?
I don't know how to get reasonable values for
AUTHOR or EMAIL, but for HOME we could
use MYDOCS/octave.  WinME seems to store
the My Documents key at
 HKEY_CURRENT_USER ->
  Software -> Microsoft -> Windows ->
    CurrentVersion -> Explorer ->
       Shell Folders -> Personal
Any idea how to query the registry?

In reviewing edit, I've addressed a long-standing
problem.  It used to require global variables, but
now I've made them all static.  The reason this was
a problem is that all global variables known to the
scope seem to be saved whenever you do something like
   global myvar='hello';
   save x
This is perhaps a bug in octave --- I certainly
don't expect variables I don't mention to be
saved along with the ones that I do.

Instead of setting the variables using global,
you will now have to use edit('variable','state')
to set the state.  I don't have anything to query
the state.  I've removed the word FUNCTION_
from all the variables since edit effectively
qualifies the name.

Another issue was that I was using EDITOR
rather than sprintf(FUNCTION_EDITOR,"")
when there is no file.  I now also change to
the HOME directory before starting the editor.

Changing the directory before starting the editor
as you have done is okay since it will work
for both windows and unix.  I haven't updated
my copy though.
