Hi Neil,

Another question:

Darcs/Commands/Optimize.lhs:110:1: Use isPrefixOf, and then remove the 
(==) test
Found:
take 4 (just_name pinfo) == "TAG "
Why not:
(4 == length "TAG ") && ("TAG " `isPrefixOf` just_name pinfo)

I assume the (==) referred to in the name of the fix is the one in the 
suggestion. Why doesn't the suggestion come with the check removed? I.e.:

Why not:
("TAG " `isPrefixOf` just_name pinfo)

Thanks,

Martijn.
