Fix various code blocks in the docs
- rst markup: put codeblock markup on separate line to make it better visible / separate it from normal text colons.
- borg help texts in archiver.py: put codeblock markup instead of colon - that way it looks like a single colon when using the cli help and also works as code block markup.
add a push-style example to borg-create docs
When I browsed the readthedocs and manpages while setting up Borg for
myself for the first time, I saw multiple hints that pushing backups via
SSH is supported (e.g. the existence of the `borg serve` command and the
`--rsh` option), but I never found a clear example. I only found
<https://borgbackup.readthedocs.io/en/stable/usage/general.html#repository-urls>
after being pointed to it by @ThomasWaldmann.
Therefore, an explicit example in the `borg create` documentation seems
appropriate. I put it next to the pull-style example using sshfs which
serves a similar usecase.
Add "SSH Configuration" section
Add "SSH Configuration" section to "borg serve" documentation, to outline ssh/sshd configuration to prevent borg serve keeping a lock on a repo in the event the ssh connection is abnormally disconnected.
In response to issues #3988, #636 and #4485 (and probably others).
drop BORG_HOSTNAME_IS_UNIQUE (please use BORG_HOST_ID if needed)
borg now always assumes it has a unique hostid - either automatically
from fqdn plus uuid.getnode() or overridden via BORG_HOST_ID.
This command works similarly to "git config" - it parses repo and
cache configs to get, set, and delete values. It only works on local
repos so a malicious client can't e.g. override their storage quota
or reset the append_only flag.
Add tests for borg config
Add documentation for borg config
Change manual config edits -> borg config
There were a couple places in the documentation where it was advised
to edit the repository or cache config file, a process that is stream-
lined by borg config.
