Follow-up Comment #2:

There's a problem with this patch, bisected to hg id 56acd8f390f8. It causes
`whos` to print its results twice.

Test: create the following two files foofun.m and fooscript.m:


$ cat foofun.m 
function foofun
  a = 1;
  b = 2;
  whos
endfunction

$ cat fooscript.m 
c = 3;
d = 4;
whos


Then call them from Octave. The function works correctly:

octave:1> foofun
Variables visible from the current scope:

variables in scope: foofun: /tmp/foofun.m

  Attr   Name        Size                     Bytes  Class
  ====   ====        ====                     =====  ===== 
         a           1x1                          8  double
         b           1x1                          8  double

Total is 2 elements using 16 bytes


But the script prints the output of `whos` twice, once in "script scope" and
once in "top scope":


octave:2> fooscript
Variables visible from the current scope:

variables in scope: /tmp/fooscript.m

  Attr   Name        Size                     Bytes  Class

         c           1x1                          8  double
         d           1x1                          8  double

Total is 2 elements using 16 bytes

variables in scope: top scope

  Attr   Name        Size                     Bytes  Class
  ====   ====        ====                     =====  ===== 
         c           1x1                          8  double
         d           1x1                          8  double

Total is 2 elements using 16 bytes


The hg id just before this patch works properly, but that doesn't have VM
support for scripts.
