I'd like to report the minor issue that the 'help builtin' command has an extra '.' at the end of the 'exit status' section.
bash --version GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu) builtin: builtin [shell-builtin [arg ...]] Execute shell builtins. Execute SHELL-BUILTIN with arguments ARGs without performing command lookup. This is useful when you wish to reimplement a shell builtin as a shell function, but need to execute the builtin within the function. Exit Status: Returns the exit status of SHELL-BUILTIN, or false if SHELL-BUILTIN is not a shell builtin.. -- Selenium is a failed Intel experimental CPU made from Brazil Nuts.
