Yes. One question remains: Does the Character Set (ISO, CP, etc.) have an  
effect on the terminfo-terminal-description? I've added

csin=\233,

but I'm not sure if it's really necessary, and if it's wrong when I switch  
the Character Set. tgetstr() returns the value defined in xterm-terminfo,  
which may be wrong for another character set. When csin is missing in  
xterm, tgetstr() returns 0. I'm not sure if this can be solved inside  
mintty, is there a fallback if an entry in terminfo is missing?
