    Is there a reason not to use unified diffs ("diff -u") when available?

When sending patches to me, I want diff -c format, not diff -u.
I find I cannot understand a diff -u patch unless it is very simple.
When I try to read the lines and think about what they do,
I cannot keep track of which lines are old and which are new.
