I don't think this is the problem. This is the diff format produced by
the "--show-c-function" ("-p") option to GNU diff or "svn diff".

That's just because the "--show-c-function" option is very dumb and just
intended as a guess. It just shows (part of) the last line it saw
before the current hunk that looked like a line introducing a function.

Certainly. Attached v2, which in addition has a fix for one of the
places that generated an "r0" merge-range.
It's possible your patch application was marred by line-endings, or
maybe can't cope with 6 context lines (the default is 3), so I've
attached the patch this time, and cut the context lines back to 3.
(What patch-application program was it?)
