When you are working with git, it can seems useless to copy old
translations in *.old files since we have access to old versions with
git. Using this setting means you do not have to remove locale/*.old
files before commit (or to add them to .gitignore). By default, *.old
files are created (this is opt-in).
Fixes typo in command given for bash_completion in README.md.
When running on linux to install bash_completion for i18n, you can run
```bash
mkdir -p ${XDG_DATA_HOME:-$HOME/.local/share}/bash-completions/completions
ln -s $PWD/bash-completions/completions/i18n ${XDG_DATA_HOME:-$HOME/.local/share}/bash-completions/completions/i18n
```
This will provide bash autocompletion for this script (you have to run
it without using `python3 i18n` command, use `./i18n.py` instead (or `i18n.py` if provided by `$PATH`)).
