    gnome-cmd-advrename-lexer.ll: fix for format-overflow
    
    gnome-cmd-advrename-lexer.cc:806:21: error: '%i' directive writing between 1 and 11 bytes into a region 
of size 7 [-Werror=format-overflow=]
    In file included from /usr/include/stdio.h:939:0,
                     from gnome-cmd-advrename-lexer.cc:19:
    /usr/include/bits/stdio2.h:34:43: note: '__builtin___sprintf_chk' output between 6 and 16 bytes into a 
destination of size 9
    
    This warning is from GCC 7
    Well, this warning may be confusing, however this says that at the line
    
    sprintf(p->counter.fmt,"%%0%ili",p->counter.prec);
    
    p->counter.prec has the size 9, while %i may take 11 bytes, so "%%0%ili" may take at most 16 bytes 
(including the terminating null character), so the buffer size may be insufficient.
