sed: appending alternate line after previous line
Hi all,
I have to append every alternate line after its previous line. For example if my file has following contents
line 1: unix is an OS
line 2: it is open source
line 3: it supports shell programming
line 4: we can write shell scripts

Required output should be
line1: unix is an OS it is open source
line 2: it supports shell programming we can write shell scripts

I think this could be done using sed, but how could i do this please help?
If it cant be done using sed then please suggest other methods

yppasswdd(4)							   File Formats 						      yppasswdd(4)

NAME

       yppasswdd - configuration file for rpc.yppasswdd (NIS password daemon)

SYNOPSIS

       /etc/default/yppasswdd

DESCRIPTION

       The yppasswdd file contains a parameter that modifies the behavior of the rpc.yppasswdd(1M) daemon.

       The yppasswdd file contains a single parameter:

	 #check_restricted_shell_name=1

       By  default in the current release, this line in yppasswdd is commented	out. If you uncomment the line, when a user attempts to change his
       default shell using `passwd -r nis -e` (see passwd(1)),	the rpc.yppasswdd daemon checks whether the  name  of  the  user's  current  shell
       begins  with  an  'r'.  rpc.yppasswdd considers any  shell whose name begins with an 'r' (for example, rcsh) to be a restricted shell. If a
       user's shell does begin with 'r', his attempt to change from the default shell will fail.

       If the line in the yppasswdd file is commented out (the default), the rpc.yppasswdd daemon does not perform the restricted shell check.

       The yppasswdd file is editable only by root or a member of the sys group.
