The program no longer dies horribly when accessing beyond the end of a device. The provided memrchr() function was fixed, as was the display after searching in modes larger than 32-bit. BLKGETSIZE is now used to try to find the size of a device.
Added many shortcuts so that F1..F12 and some others works on
more terms (xterm, rxvt, sgi's winterm...), removed the scanw that's
badly handled on sgi (replaced by getstr + sscanf), now displays the
reached offset while searching and manpage update.
