Please ensure your git log wraps at around 72 chars to ensure it isn't
truncated in the git log output in a typical terminal.

Please be consistent with whitespace above. I prefer TABs be used
exclusively for indentation with spaces used for alignment. The above is
purely alignment. However, others prefer TABs for as much of either as
possible. Either is fine, but it must be consistent throughout the file.
In this case, please use spaces.
