Use this trick:

1. Install  odt2txt  (Linux:  sudo apt-get install odt2txt , Mac:  brew install odt2txt ).
   

2. Add to  .gitattributes :

   *.odt diff=odt 

3. And to  .gitconfig :

   [diff "odt"]
       textconv = odt2txt
       binary = true

4. Of course it will work better if you have cloned this project :), and are fetching updates, and run commands like  log . (But you should see the diffs even in GUI tools like  gitk .)

   To see the  log  of 20 last commits I use

   $ git --no-pager log --max-count=20 -p --word-diff=color

   And for  diff :

   $ git --no-pager diff --word-diff=color 

   Probably, there should be another trick, to keep the words unsplit, but I haven’t figured it out yet.
