The docu for `Popen.wait()` says:

If for some reason uncrustify gets angry at our file and indent on/off
marks, it will result in an error code other than 0. Since in those
cases there is no output to diff with, we misinterpret those situations
as "the whole file should be deleted", which is far from it.

Borrowed from Tracker, this script has different mode usages:
* --sha allows specifying a commit SHA, HEAD^ by default.
* --dry-run shows suggested changes in stdout, by default
the local tree is changed.
* --rewrite amends the last commit, in addition to performing
the changes.
This allows from simple style checks in the development tree,
automatically rewriting with the suggested changes (e.g. with
`git rebase --exec ./check-style -r`) and CI integration.
The script has per-function granularity, and works by re-styling
individually every commit, and inside every commit every chunk.
