It turns out the breakage was caused after merging Fredrik's improvements. I'm double-checking the fix and will be pushing out corrected "master", "next" and "pu" shortly.

Sorry, Fredrik.

Subject: [PATCH] blame: unbreak "diff -U 0".

The commit 604c86d15bb319a1e93ba218fca48ce1c500ae52 changed the original "diff -u0" to "diff -u -U 0" for portability.

A big mistake without proper testing.

The form "diff -u -U 0" shows the default 3-line contexts, because -u and -U 0 contradicts with each other; "diff -U 0" (or its longhand "diff --unified=0") is what we meant.
