  16  * This also bypasses the usual "convert-to-git" dance, and that is on
  17  * purpose. We could write a streaming version of the converting
  18  * functions and insert that before feeding the data to fast-import
  19  * (or equivalent in-core API described above). However, that is
  20  * somewhat complicated, as we do not know the size of the filter
  21  * result, which we need to know beforehand when writing a git object.
  22  * Since the primary motivation for trying to stream from the working
  23  * tree file and to avoid mmaping it in core is to deal with large
  24  * binary blobs, they generally do not want to get any conversion, and
  25  * callers should avoid this code path when filters are requested.
