an issue:

$echo '."\\\\l ~","/nonexisting.k"' >/tmp/f.k
$q /tmp/f.k
-try to exit with ctrl-d (bunch of parentheses gets printed and terminal gets unresponsive)
-or seg faults (i haven't been able to tell, will update when i can distinguish) 
-this happens because of "~" character in the path i don't expect it to understand HOME or anything but it should fail properly.


another issue:

builtin repl would be better if
-cb:left
-cf:right
-cp:up
-cn:down
-md:delete-next-word


another issue(this is fixed, ignore): 

\c 0N 0N
doesnt work.
suggestion: maybe use something like this for updating termR and termC:
void update\c(){
 struct winsize w;int f[]={1,0,2},i,t;
 for(i=0;i<3;i++)if(isatty(f[i])&&!ioctl(f[i],TIOCGWINSZ,&w)&&w.ws_row&&w.ws_col){termR=w.ws_row;termC=w.ws_col;return;}
 t=open("/dev/tty",O_RDONLY);if(t>=0&&!ioctl(t,TIOCGWINSZ,&w)&&w.ws_row&&w.ws_col){close(t);termR=w.ws_row;termC=w.ws_col;return;}if(t>=0)close(t);
 char*l=getenv("LINES"),*c=getenv("COLUMNS");if(l&&c){termR=atoi(l);termC=atoi(c);return;}
 termR=12;termC=57;}
