Yes, this code works with a little hack. Thank you.
I'm scared to ask: what pray tell is this little hack?
Looking at it again, probably making it work at all, because I never
consumed the "Log for " lines, so produced an infinite list of empty
lists
:-/
Oh, yeah, I've done that before (with custom chunking functions, etc.).
Who hasn't?

Just so you know, the split package might already have a function to do
what you want...
Sort of. Not one function, but the building blocks:

import Data.List (isPrefixOf)
import Data.List.Split

msplit = split (keepDelimsL $ whenElt ("Log for " `isPrefixOf`))

I think. But who looks at API docs in the dead of the night when cooking up 
the function seems so easy :)
