Digging in to some of the meatier backlog today. Backlog down to 225.

A lot of fixes around using git annex enableremote to add new gpg keys to a gcrypt special remote.

Had to make git-annex's use of GIT_SSH/GIT_SSH_COMMAND contingent on GIT_ANNEX_USE_GIT_SSH=1 being set. Unfortunate, but difference from git made at least one existing use of that environment variable break, and so it will need to be whitelisted in places where git-annex should use it.

Added support for git annex add --update
