[PATCH 0/4] a few minor buffer cleanups in fast-import

I don't think any of these is a triggerable bug. They're just cleanups to make it more obvious that the code is doing the right thing (and making it harder to do the wrong thing).

  [1/4]: fast-import: use xsnprintf for writing sha1s
  [2/4]: fast-import: use xsnprintf for formatting headers
  [3/4]: encode_in_pack_object_header: respect output buffer length
  [4/4]: pack.h: define largest possible encoded object size
