My answer is the same. Some users write programs that explicitly support
calls under different versions. Sometimes you have to look inside to see
that; part of the art is often concealing the cleverness from the user. 

In any case, anybody can call anything under different versions <= their
current Stata version; the question is whether it makes any difference.

To clarify, I know that lots of people like you will provide a 
foobar8, foobar7, etc. when you release a new version.  By version 
control, I was thinking of how Stata does it, e.g.

version 7: foobar

which would cause foobar to revert to its version 7 behavior.  I 
don't know of any user written programs that do that, i.e most 
programmers just seem to write a foobar7, a foobar8, etc.  But, I 
could be missing some.
