[man BUG] SY/YS doesn't break the line before the first cmd arg

[Alejandro Colomar]

Hi Branden,

I met a bug in SY/YS.  Here's a reproducer:


        alx@devuan:~/tmp$ cat syys.man 
        .TH a s d f
        .SH g
        .SY foo
        bar
        .YS .
        .SY fooooooo
        baaaaaaaaaaaaaaaaaaaar
        baaaaaaaaaaaaaaaaaaaaz
        qwwwwwwwwwwwwwwwwwwwwe
        zxxxxxxxxxxxxxxxxxxxxc
        .YS .
        .SY fooooooooooooooooooooooooooooooooooooooooooooooooo
        baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaar
        .YS
        alx@devuan:~/tmp$ groff -man -Tutf8 syys.man 
        troff:syys.man:13: warning [page 1, line 7]: cannot break line
        a(s)                                                                    
    a(s)

        g
             foo bar
             fooooooo baaaaaaaaaaaaaaaaaaaar baaaaaaaaaaaaaaaaaaaaz
                 qwwwwwwwwwwwwwwwwwwwwe zxxxxxxxxxxxxxxxxxxxxc
             fooooooooooooooooooooooooooooooooooooooooooooooooo 
baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaar

        f                                       d                               
    a(s)

I expect that in the third command, ba*ar should be put on the next line
and indented.
