Bash, mostly, but also ksh and zsh; sorry for not mentioning this. I now see 
that the root account usually does not change the behaviour of cd, so we may 
as well forget about the matter. My thought was: if a small change helps 
avoid this problem (which I think can occur easily enough), it could be 
helpful. Incidentally, IMHO the way it is coded in INSTALL.in (I didn't know 
about INSTALL.in, sorry) is a bit unusual; cd does not seem to be required by 
the POSIX standard to have non-zero exit status when it fails (and in fact, 
on older SunOSes, 'cd non/existant/directory' returns 0). But that is 
probably more a matter of style, more than anything else. Regards,
