> - Update from 5.1.012 to 5.1.016
> - Update of rootfile not required
> - Changelog
>    Patch 013 - Bash did not always perform tilde expansion following an unquoted colon on
>                the rhs of an assignment statement in posix mode.
>    Patch 014 - Bash may produce corrupted input if a multibyte character spans a 512-byte
>                boundary while reading the output of a command substitution.
>    Patch 015 - There are some characters (e.g., cyrillic) that can't be displayed using
>                certain single-byte encodings (e.g., cp1251) because the negative signed
>                int is interpreted as EOF and not displayed.
>    Patch 016 - Multiple `!' tokens should toggle negation of an expression in a [[
>                conditional command, instead of simply negating the expression.
