Why does stylus generate css incorrectly (skips; etc)?

Question

css

there is a code:

STYLUS

body
    background #eee

#one
    width 150px
    height 150px
    background red
    @media print
        display none

#two
    width 100px
    @media print
        display none

When converted to native CSS, it outputs something like this:

body{
    background: #eee;
}
#one{
    width: 150px;
    height: 150px;
    background: red // не случайно пропустил ; stylus пропускает часто..
}
#two{
    width: 100px // тоже пропускает часто ;
}

@media print{
    #one{
        display: none;
     }
}
@media print{
    #two{
        display: none // и тут пропустил ещё ;
    }
}

Why doesn't it concatenate media into 1 and skip the ; etc ?

If something is not generated correctly from stylus to css, then either you have errors (syntax, etc.), or these are generator jambs. How do you generate css from stylus?
