Details:
Hi all,
While studying the code with the idea of adding support for xterm's new
"extended mouse mode" I noticed the following near display.c:3575
if (i > 5 && bp[0] == 033 && bp[1] == '[' && bp[2] == 'M')
{
bp++;
i--;
}
else if (i < 5 || bp[0] != 0233 || bp[1] != 'M')
continue;
The second conditional looks like a bug to me, based on what I know of vt200
mouse codes (bp[0] should never contain '0233' and 'M' should live in bp[2],
not bp[1]).
Can somebody confirm whether this is a latent bug? Also, is there a reason
why this wouldn't work:
if ( i < 5 || bp[0] != 033 || bp[1] != '[' || bp[2] != 'M')
continue;
bp++;
i--;
Regards,
Ryan
