I can confirm it happens, but DifferenceEngine.php is too terrible for mere mortals to
comprehend.

Here are more numbers separated with "," other countries are using ".". Please
change the code that diff sees three "number strings" . Compare only sequences
of characters between 0 and 9, do not include ",", ".", "e" or "E" as in 10E3.

Please note that only the testcases from
bug 2824: diffs and literal compare of numbers fails
are fixed. I will reopen bug 2824 because "30,000,000" is a valid number.

Will tray to generate the test cases from bug 349 comment 8.

Do not use anything on Wikimedia sites at this time for testing the internal
diff engine, as we're using an external diff engine now (wikidiff2).

Seems to have been fixed some time ago.
