[PATCH v4 0/4] add new GIT_NO_REPLACE_OBJECTS env variable

Here are all the patches together.

The other change (except putting them together) is that I tried to improve the commit messages as suggested by Paul and Junio.

The first patch contains documentation fixes and could be applied to "maint".

Christian Couder (4):
  Documentation: fix typos and spelling in git-replace documentation
  replace: use a GIT_NO_REPLACE_OBJECTS env variable
  gitk: add "--no-replace-objects" option
  Documentation: replace: talk a little bit about
    GIT_NO_REPLACE_OBJECTS
