Details:

I noticed this odd behavior crop up recently with "clear all" and "whos". It
does not break any of my code, but I thought I should report it if it is a
symptom of something deeper.

Try running the following from the octave command prompt:


clear all; clc; i = 20; j = 10; k = 50; foo = 23; whos; clear all; whos


On my system (Ubuntu 12.04.1 64 bit on x86_64) the output is:


Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        foo         1x1                          8  double
        i           1x1                          8  double
        j           1x1                          8  double
        k           1x1                          8  double

Total is 4 elements using 32 bytes

Variables in the current scope:

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        foo         0x0                          0  unknown
        i           0x0                          0  unknown
        j           0x0                          0  unknown
        k           0x0                          0  unknown

Total is 0 elements using 0 bytes


HOWEVER: creating a .m script file with the above line of code and then
calling that script makes "clear all" work properly, and the second "whos"
does not list any variables in that case. 

Could someone please verify this behavior?
