Do not show file prefix, this removes a/ and b/ prefix from file paths.
This eases copying file names from diff output.
Also adjust hot git handles whitespace to improve diffing, especially
for one customer where
`git diff -U0 --word-diff-regex='[^[:space:]]' HEAD~1` is possible now.
Remove flakes for now.
I will use shells for now to not have a mixed setup.
Add composer v1 for a single customer project as overlay due to usage in
shell instead of flakes.
Adjust folder to not have unnecessary deep structure.
Add shell for reuter monorepo using composer v1.
I tried nvimpager but it was a bit complex for me to re use existing
Neovim settings tweak for specific usage as pager.
I decided to stick with less for everything.
