test: Add a new --quiet flag to suppress output

The --quiet flag is useful when only the exit status matters.

Fix the documentation for the -t flag to no longer claim that `type` can
print "keyword", as it never does that.

Stop printing a blank line for functions/builtins when the -p flag has
been passed. It's just not useful.

 - \c -h or \c --help prints help and then exits.
 - \c -a or \c --all prints all of possible definitions of the specified names.
 - \c -f or \c --no-functions suppresses function and builtin lookup.
-- \c -t or \c --type prints <tt>keyword</tt>, <tt>function</tt>, <tt>builtin</tt>, or <tt>file</tt> if \c NAME is a shell reserved word, function, builtin, or disk file, respectively.
+- \c -t or \c --type prints <tt>function</tt>, <tt>builtin</tt>, or <tt>file</tt> if \c NAME is a shell function, builtin, or disk file, respectively.
 - \c -p or \c --path returns the name of the disk file that would be executed, or nothing if 'type  -t  name' would not return 'file'.
 - \c -P or \c --force-path returns the name of the disk file that would be executed, or nothing if no file with the specified name could be found in the <tt>$PATH</tt>.
+- \c -q or \c --quiet suppresses all output; this is useful when testing the exit status.
 
 \c type sets the exit status to 0 if the specified command was found,
 and 1 if it could not be found.
