Bash Version: 3.0
Patch Level: 13
Release Status: release

Description:

`pushd DIR' fails to work if DIR starts with a hyphen.
Using `pushd -- DIR' does not help.


Repeat-By:

mkdir -- -foo
builtin pushd -- -foo
bash: pushd: -foo: invalid number
pushd: usage: pushd [dir | +N | -N] [-n]


Fix:

pushd_builtin checks for a "--" option twice. Removing the first check
fixes this problem, but might cause another one (I don't know
if the first "--" check was doing something useful).
