Adds a small warning indicating that b2 bucket names need to be unique. It's an easy mistake to make, and it's surprising to get the following error if you're not accustomed to the way B2 works:
Fatal: create repository at b2:postgres failed: NewBucket: b2_create_bucket: 400: Bucket name is already in use
Add documentation around using default Google application credentials,
along with a changelog extra that describes the feature and the
potential impact on existing restic uses (read: none).
This commit refactors the documentation according to my proposal in #1273
and the discussion I had with fd0 on IRC.
The bits from the manual that I could not immediately put into the new
structure are contained in manual_rest.rst Anything else is still there,
nothing has been deleted.
I changed the heading markup to follow the convention used in Python’s
Style Guide for documentation, this convention is explained in a comment
at the top of every file.
I also added a paragraph on installing restic on Debian.
