Description:
Setting OLDPWD to anything other than an absolute path causes
`cd -` to behave incorrectly, defaulting to ./$OLDPWD instead of
being equivalent to `cd $OLDPWD` per POSIX requirements.
Thanks for the report. The upcoming issue of POSIX says that if you set
OLDPWD to something, all bets are off and the shell can do what it wants,
but it's reasonable to handle this case.
