git-prompt, flake8, pass-git-helper, gpg trust model, SSH control master, python indent

1. Before we had no real inclusion of git-prompt in this repo. Now, we have
   included git's own git-prompt. Alternatives were tested and failed to
   meet KISS, YAGNI, or one-task-one-solution principles.
2. Include $HOME/go/bin in PATH
3. Set flake8's max-cognitive-complexity to 16
4. Set up pass-git-helper as git's credential helper, set pack.windowMemory to 1024m
5. Set trust-model of GPG to tofu+gpg
6. Do not use tabs in python anymore, bow to global byte-consuming standard
7. Do not use SSH ControlMaster as default anymore

+## only clone git-prompt.sh
+
+This repository does not include a git-prompt.sh source. This is due to the file residing inside
+the whole git repository. Submoduling cannot just include one file, so if you need this file here,
+the checkout is... up to you, kind of.
+
+Since I am maintaining this repo for ease of distribution for myself as well, here's the solution:
+
+Trigger `/.githooks/post-checkout` inside this repo. Either do this on any checkout, or set your git
+post-checkout trigger for this file to automatically take over.
+
+## sha1collisiondetection
+
+For git-prompt, its submodule sha1collisiondetection may be "broken" (i.e. it cannot be pulled), here's a fix:
+
+`git -c submodule.sha1collisiondetection.update=none COMMAND`
+
+...whereas `COMMAND` is one of the usual actions such as
+
+```
+clone --recurse-submodules
+submodule update --init --recursive
+```
+
+This only applies if you do not use `/.githooks/post-checkout` inside this repository.
