Hi,
Very clever and very useful, although on my box it does not work
for the specific case (octave-2.1.64 on a debian testing box).

749/mnt/avraham/downloads> help OCTAVE_FORGE_VERSION
OCTAVE_FORGE_VERSION is the user-defined function from the file
/usr/share/octave/2.1.64/site/m/octave-forge/miscellaneous/OCTAVE_FORGE_VERSION.m

OCTAVE_FORGE_VERSION The release date of octave-forge, as integer YYYYMMDD

But, apparently on my box, if called before this command, the
output of whos does not contain the string FORGE. Only after
asking help OCTAVE_FORGE_VERSION, can whos -all to find
OCTAVE_FORGE_VERSION, as a user defined function...
Is that something that changed in the more recent versions, or
you also happened to find OCTAVE_FORGE_VERSION, using whos -all
only after unintentionally telling the system about it ?

You can find OCTAVE_FORGE at any stage with your trick by 
using the command help instead of whos -all. Its disadvantage is 
that, if the question is vague (say that you just ask the search for
forge, with case sensitivity off, as suggested) the search
function gives a lot of irelevant hits. But you do get the
sought-for function as well.
Cheers, Avraham
