ash: add support for bash 'function' keyword
Where the POSIX shell allows functions to be defined as: name () compound-command [ redirections ] bash adds the alternative syntax: function name [()] compound-command [ redirections ] Implement this in ash's bash compatibility mode.

The other two variants work: f() (echo "ok") function f() (echo "also ok") function old new delta parse_command 1555 1744 +189 tokname_array 232 240 +8 .rodata 155612 155566 -46 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 197/-46) Total: 151 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
