Nothing shocking here:
- division by zero now reported on the application rather than the
operator
- renumbering of printed bindlib variables
- some whitespace changes
This helps have a reasonable `git blame` experience even in the presence
of reformat commits, by explicitely digging deeper when they are
encountered.
Use `git config --global blame.ignoreRevsFile .git-blame-ignore-revs` to
enable it locally.
