Index descriptions are limited to MAXINDEXSIZE (60) chars. Any description
beyond that is truncated. Also, only the first line is displayed as well.
This allows pkg_info -a -I to be formated in two columns with one line
per package for easy reading.

-q turns on "quiet" mode, where informational headers and such are not
dumped, just the information.
-L Shows full pathnames of files comprising a package. With -q,
this can be useful for doing fileset operations, such as
"du -s `pkg_info -q -L foo_bin`" to see how much space package
"foo_bin" is taking up.
