 It has already occurred in the past in `testsuite.git` repo, that
 executables were checked in by accident, and caused the Git history to get
 bloated.

 In order to avoid such accidents in the future a Git hook script in the
 style of [http://stackoverflow.com/questions/20226132/is-there-a-git-hook-
 which-can-prevent-binary-check-ins this] might be useful, but taking also
 into account the size, and/or possibly with a magic safeword to be put in
 the commit message, to override the check for a single commit, if the
 author really knows what (s)he's doing.
