Rewrite git-slurp to have "some" style
* Die by dedicated function.
* Push only if allowed (a line containing single word PUSH found in
.git-slurp-ok file)
* Allow working when deeper in git repo (but not if outside).
* Make permisson code readable (self-doc).
* Enclose in main() to allow for better hygiene.
