https://github.com/facebook/hhvm/pull/3805.patch has as part of it:
```
diff --git a/hphp/test/slow/object_property/invalidWith__get.php.expectf b/hphp/test/slow/object_property/invalidWith__get.php.expectf
index 033c3ac88947362c4227a3ae44d556d5d2665ef0..0dd4757a6bbe6cd99b57f092f3a5e69a4158fce3 100644
GIT binary patch
delta 21
ccmey(*vd4agxfi>Bsn87DJNASZDMH~09UpM8~^|S
delta 11
ScmZo=`pr0@gwbtceH#E7tpsHN
```
And when parsing it I'm getting `Expected 'literal NNNN' to start git binary patch`.
Your code looks like it isn't happy with the word `delta` and instead wants only `literal`.
