Add a new option -s. With this option pkg_search(1) will display the …

…description

of a package.  This is very helpful it you want to know more about a package.

% pkg_search -s host-20040812
Host is a very powerful DNS query and testing command-line tool. Major
differences with the ancient version of the program with the same name
[...]

Note:  You need the complete pkgsrc tree to use -s.

While here:
 o Whitespace fixes
 o Remove unused split commands
 o Bump copyright to 2008.
