patchsaving

If two users concurrently edit a page, then only the first save
attempt will succeed; which the second user is told by the "This
page version was already saved" failure message.

This plugin works around this by passing the contents of the
concurrent versions through the 'diff' and 'patch' utilities, which
often merges the two different modifications in a new version that
can be saved into the database so there is no need for the failure
message.

You cannot modify the README.plugins file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.plugins.Discussion.
