Conceptually, this isn't much different from a summary. say we decide
that 8-50 chars is a reasonable default summary length, and add text
to shorter summaries. Some simple possible cases:
1) minor edit. one word changed, no summary. summary changed to read
"'// word1 --> word2"
2) minor edit. a few words changed, summary 'typos'. summary changed
to read "typos // word1 --> word2, word3 --> word4, ..."
3) major edit. a few sentences moved around. summary "rewrite".
summary changed to read "rewrite // 'Start of first old changed
para...' --> 'New paragraph...' "
Or rather than changing summaries, which might
actually be metadata
useful for something in the future, we should make the places where we
see lists of changes (history, RC, etc) show some of the change text
itself.
We could also add ways to see a larger chunk of changed text; this is
just a simple suggestion for enhancing the current interface (and the
metadata in the database)
