Description of problem:
If the server returns the header Content-Disposition, and the -P argument is
supplied to wget, then wget will ignore the -P argument and store the file in
the current working directory.

Version-Release number of selected component (if applicable):
# rpm -q -i wget
Name        : wget                         Relocations: (not relocatable)
Version     : 1.10.2                            Vendor: Red Hat, Inc.
Release     : 7.el5                         Build Date: Tue 09 Jan 2007 11:12:03

# wget --version
GNU Wget 1.10.2 (Red Hat modified)

How reproducible:
Pass the '-P' argument and a directory path to wget. Also pass a URL for which
the server will reply with the Content-Disposition header.

Steps to Reproduce:
1. For example, create a directory /home/user/tmp and run a server on localhost
port 80 with netcat.
/home/user$ mkdir tmp
/root# nc -l -v 127.0.0.1 80

2. Connect to the server with wget and instruct it to store the downloaded file
in the tmp directory.
/home/user$ wget -P tmp http://127.0.0.1/foobar

3. On the netcat server side, paste in content similar to below.

HTTP/1.1 200 OK
Date: Mon, 10 Mar 2008 14:57:36 GMT
Server: Apache/2.2.3 (CentOS)
X-Powered-By: PHP/5.1.6
Content-Disposition: attachment; filename=foobar
Content-Length: 10
Connection: close
Content-Type: application/gzip

1234567890

Actual results:
The file is stored in the current working directory of wget (/home/user).

Expected results:
The file should be stored in the relative directory of tmp (/home/user/tmp).

Additional info:
This argument worked correctly on RHEL 4. If you omit the Content-Disposition
line, then the file is correctly stored in /home/user/tmp.
