With this one, I get:

$ git apply < p2.diff   
error: patch failed: pre.txt:1
error: pre.txt: patch does not apply
$ patch < p2.diff 
patching file pre.txt

=> no fuzzy matching for patch, git apply should actually work.

I am not sure what you are trying to do with that patch that tries
to touch the same line twice.  Is this the same old laziness coming
back to bite us, the one that we attempted to work around with
933e44d3 ("add -p": work-around an old laziness that does not
coalesce hunks, 2011-04-06)?

In other words, isn't the right fix to coalesce that input, so that
the second hunk does *not* require fuzzy application in the first
place?
