What shells are these? You don't give an example that causes trouble, and
in particular no way to reproduce this.
The behaviour you describe is prohibited by the POSIX standard, so the
problem would appear to be with the unnamed shell. I can see how it could
happen if a user redefines 'cd', but then a user could redefine all the
commands in his OS and we have to make some reasonable assumptions
You seem not to have submitted a patch against the R sources, which
contain src/scripts/INSTALL.in, not INSTALL, and it contains changes you
do not mention.
