Hi Hans

Actually i can , I should've cut off the '\r' 😊 ,  this is what was causing the term to go bend

This is the correct diff (option -C 9999 doesn’t worked with -u)
I also included your code for the pts anyway

Works fine here

Thanks

Hi Ivan,

I think you should upload the diff at:

https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Freviews.freebsd.org%2Fdifferential%2F&amp;data=05%7C01%7C%7C85e3f391dfc941f2852908da5457c75f%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637915033252675801%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&amp;sdata=4sxXIR9NhIbwD42gIrP4pYcdnUinqae1SNZAjclr2Aw%3D&amp;reserved=0

Make the diff like this:

diff -u -C 999999 sys/dev/vt/vt_buf.c.orig sys/dev/vt/vt_buf.c > a.diff


I see two issues:

1) Pointer arithmetics is not so good!

I think this would be better and avoid the ">" with pointers!

for (end = buf + i; end-- != buf; ) {
    if (isspace((unsigned char)*end) == false)
	break;
    *end = '\0';
}

Can you explain this:

> -                       buf[i++] = '\r';
> +                       buf[i] = '\r';
>                         buf[i++] = '\n';

'\r' character is now overwritten by '\n' character.
