The other day I saw a change described as "Added
a word.". Yes, but
/which/ word?
If you want to know which word, you can look at the diff. What I'd
want to know is *why* they added it. "Added missing word", perhaps -
then you know it was a mistake the word wasn't there before. "Added
word to clarify", "Added word to disguise the fact that my employer
eats babies", etc. would be useful information.
