Enhancement: Support pruning even after running out of disk space

When running out of disk space it was no longer possible to add or remove
data from a repository. To help with recovering from such a deadlock, the
prune command now supports an `--unsafe-recover-no-free-space` option to
recover from such situations. Make sure to read the documentation first!

prune: Add unsafe option to recover from no free space The new option allows prune to operate with nearly no scratch space by only removing no longer necessary pack files and first deleting the index before rebuilding it. By first deleting the index it becomes safe to just delete no longer necessary pack files. However, as a downside there's now the risk that the repository becomes inaccessible if prune fails. To recover from that problem a user might have to manually delete the repository index and then run (a full) `rebuild-index` again. 2021-08-16 14:02:01 +00:00			`Enhancement: Support pruning even after running out of disk space`
