The default line of sight radius in Crawl is about 8, reduced to 6 when wielding a lantern of shadows. (Actually, it is sqrt(65), so the field at (8,1) is in sight.)
The following drawing shows fields within the default field of view with their grid distance.

In 0.7, the developers made an undocumented change to the LOS. Ranges are circular now, so every spell and ability that reaches a set distance got about two squares lopped off the diagonals. Stealthy characters can now reach their target in 5 squares (instead of 8) at certain angles.
