git-annex/Command/RecvKey.hs
Joey Hess b81d662cbf Avoid repeated location log commits when a remote is receiving files.
Done by adding a oneshot mode, in which location log changes are written to
the journal, but not committed. Taking advantage of git-annex's existing
ability to recover in this situation.

This is used by git-annex-shell and other places where changes are made to
a remote's location log.
