[PATCH 0/4] extend smudge/clean filters with direct file access

As discussed in this thread:
http://thread.gmane.org/gmane.comp.version-control.git/294425
This adds smudge-to-file and clean-from-file commands supplimenting the
smudge and clean filters.

This interface can be much more efficient when operating on large files,
because the whole file content does not need to be streamed through the
filter. It even allows for things like clean-from-file commands that avoid
reading the whole content of the file, and for smudge-to-file commands that
populate a work tree file using an efficient Copy On Write operation.

Joey Hess (4):
  clarify %f documentation
  add smudge-to-file and clean-from-file filter configuration
  use clean-from-file in git add
  use smudge-to-file in git checkout etc
