This thought occurred to me, but really, how often are you going to
have a 10 GiB **text** file with no newlines? Remember, this is for
text (log files, INI-style configs, plain .txt), not binary (HTML,
XML, JSON). Off the top of my head, I can't think of any case where
you'd expect to see 10 GiB in a single line.

In the worst case, you can just use "decode" to process bytes coming
from the ByteString-based enumHandle, which should give nicely chunked
