where texts starting lines 712 and 737 respectively are
compared, 4 paragraphs of 3 to 14 words each were
deleted, but the first, reading

[[Organizational theory]] - needs spell checking,

paragraphs
is shown as being changed to the text of the 1st non-
deleted one following those 4, which reads

[[Wen Tianxiang]] unwikified

(The other 3 deleted 'graphs are accurately shown as
deleted.)

This diffs output does not misdescribe the contents of
the texts, and i know this is an expensive task to do to
the satisfaction of wet-ware. But i have the impression
WP usually does it much better than this one, so
possibly this exercises a bug that makes the algorithm
give up a little early at trying to match the Wen
Tianxiang graf in the two versions.

Thanks for your attention, and all the development
effort.
