Heh, this is by no means the weirdest thing about /bin/sh ;-)
Check out the UNIX98 spec sometime, well you probably saw
g_shell_parse_argv() - /bin/sh can basically only be specified by
explaining what algorithm you have to use in order to do everything,
there's no way to give a grammar or anything sane like that.
