st: ivprobit and overid

[Kit Baum <baum@bc.edu>]

The Baum-Schaffer-Stillman team recently released a version of - 
overid- (test of overidentifying restrictions) which works after  
ivprobit, ivtobit and reg3. The help for use after ivprobit indicates  
that 'until official Stata is fixed' you should use the depvar()  
option to indicate the dependent variable in your ivprobit. Well,  
official Stata was fixed, but not in such a way that our routine  
works unless you use the depvar() option. We will issue a fix that  
corrects for their fix presently. (The prior version of ivprobit did  
not provide e(depvar). The new version does populate e(depvar), but  
with multiple variables).

The existing version of overid on SSC will work fine with ivprobit as  
long as you specify the depvar() option.
Thanks to Hiroyuki Kawakatsu for bringing this to our attention.
