- By default treat supplied arguments as a shell globs to be matched against

names of installed packages;
- add new `-G' option to disable glob matching and revert to previous
  behaviour (I have no idea why this could be necessary, though);
- add a new `-x' option, which instructs pkg_info(1) to treat supplied
  arguments as a regular expressions.

For example:
$ pkg_info foo\* - displays information about all packages whose names start
		   from foo
$ pkg_info -G foo\*-1.1 - displays information about package named "foo*-1.1"
$ pkg_info -x ^foo.\* - displays information about all packages whose names
			start from foo
