Thanks for your suggestion. However, a binary diff would look like this which 
isn't great for seeing what's going on during review:

  diff --git a/tests/ref/fate/sub-webvtt2 b/tests/ref/fate/sub-webvtt2
  index 357b8178ea1cf224ad47dcf78b24f1948ece6665..4cd1d86a9a58ccf65812131bf84a17531c2c6cfa 100644
  GIT binary patch
  delta 24
  gcmeys^NnXiIV;bjhJHgMV-r)eM-6?GYgs=70DwpeRR910
  
  delta 18
  Zcmeyy^MPkWIV+o?k+F%X+2m%{&j3Hw26O-b

Also as noted, locally plain `git am` has no issues applying the regular 
(non-binary) patch; iirc patchwork uses some additional flags to make it more 
restrictive because regular codefiles shouldn't use CRLF line-endings.

I recall using some .gitattribute settings to force crlf (without making 
the file binary?) were discussed last time this happened, but deemed to be not 
worth it because of some other issues with it.
