added highlighting to disabled commands in GNU bash, version 4.1.5(1)-release (i486-pc-linux-gnu)

These shell commands are defined internally.  Type `help' to see this list.
Type `help name' to find out more about the function `name'.
Use `info bash' to find out more about the shell in general.
Use `man -k' or `info' to find out more about commands not in this list.

A star (*) next to a name means that the command is disabled.
