is diff-fixup-modifs supposed to work on regular diff?

[Samuel Wales]

I have been trying to edit diffs, which are in regular <> style, and
run diff-fixup-modifs.  My goal is to programmatically get rid of
empty hunks and to renumber edited hunks.

For this particular purpose, which is not a one-off that can be fixed
manually but an
ongoing need, I cannot use the otherwise superior unified or context diff.

Thanks.

diff-fixup-modifs (and most of diff-mode's editing functions such as
the killing of hunks) only works for context diffs, because it does not
preserve line numbers precisely.

Thanks for the explanation.  I will then somehow have to solve the
problem differently.

What I really want is a way to tell Ediff to make certain lines (not
difference regions) context lines instead of changes, even when they
are changes.
