This seems underspecified; there are two diff_change calls in diff-lib,
and the call in show_modified() is not changed in this patch.

The function name is very generic, and it's not clear:
- What this does besides calling "diff_change()".
- When I should call this instead of "diff_change()".
- What the return value means.
Both of these should be documented in a comment, and I also suggest
renaming the function.

If I'm reading the indentation correctly, the "continue" comes right
before the end of the for-loop block, so it's a no-op and should be
removed.
