 * In the POSIX teleconferences from November and December 2014, we

 * Special built-in utilities and intrinsic utilities are called before any
 * attempt for a PATH search is done.
 * Special built-in utilities in addition keep variable assignement in effect
 * after the builtin completes.
 * See http://austingroupbugs.net/view.php?id=854#c2495 for the new POSIX
 * classification of shell builtins.
 *
 * Built-ins marked with "S" are POSIX special built-in utilities.
 * Built-ins marked with "I" are POSIX intrinsic utilities.
 * Built-ins marked with "i" may not be permitted intrincics in the future.
 * Built-ins marked with "-" do not follow utility syntax guidelines.
 * Built-ins marked with "U" follow utility syntax guidelines and support --.
