git-workflow: revamp
Our recommended Git workflow went through many iterations over the past few years, with the initial method (manual import from a README repo) almost eradicated now, in favor of: collaborating / forking / gbp-import-dsc.
The documentation was often edited locally but never revamped to get rid of many left-overs that hinders proper understanding.
Hopefully this is done now :)
- Re-order to clarify import methods, most recommended first
- Drop historical left-overs recommending previous methods
- Replace hackish manual import with gbp import-dsc
- Document debian/-only repos
- Recommend overwriting gbp.conf
- Misc fixes and updates
