I believe it is a good practice too keep each line short and
easy to read. The following is taken from python style
guide.
Maximum Line Length
Limit all lines to a maximum of 79 characters.
There are still many devices around that are limited to 80 character
lines; plus, limiting windows to 80 characters makes it possible to have
several windows side-by-side. The default wrapping on such devices
disrupts the visual structure of the code, making it more difficult to
understand. Therefore, please limit all lines to a maximum of 79
characters. For flowing long blocks of text (docstrings or comments),
limiting the length to 72 characters is recommended.

P.S. We really need such a well written style guide for
haskell. Python has this nice PEP (Python Enhancement
Proposals). Should we start making our own HEP?
