No, Greg's (and Martin's) is a valid argument. Sometimes, like in
Delphi, the supplier changes the file format from binary to text, or
vice versa, so there is a genuine possibility that blame is only valid
for some of the file's revision history. There is already an option to
start from revN, but there does need to be an option to skip/include
revs marked as binary. What the default should be is open to (yet more)
debate.
