[PATCH 6/6] grep: make it clear i-t-a entries are ignored

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

The expression "!S_ISREG(ce)" covers i-t-a entries as well because
ce->ce_mode would be zero then. I could make a comment saying that, but
it's probably better just to comment with code, in case i-t-a entry
content changes in future.
