Joey Hess e213ef310f git-annex (5.20140717) unstable; urgency=high
* Fix minor FD leak in journal code. Closes: #754608
  * direct: Fix handling of case where a work tree subdirectory cannot
    be written to due to permissions.
  * migrate: Avoid re-checksumming when migrating from hashE to hash backend.
  * uninit: Avoid failing final removal in some direct mode repositories
    due to file modes.
  * S3: Deal with AWS ACL configurations that do not allow creating or
    checking the location of a bucket, but only reading and writing content to
    it.
  * resolvemerge: New plumbing command that runs the automatic merge conflict
    resolver.
  * Deal with change in git 2.0 that made indirect mode merge conflict
    resolution leave behind old files.
  * sync: Fix git sync with local git remotes even when they don't have an
    annex.uuid set. (The assistant already did so.)
  * Set gcrypt-publish-participants when setting up a gcrypt repository,
    to avoid unncessary passphrase prompts.
    This is a security/usability tradeoff. To avoid exposing the gpg key
    ids who can decrypt the repository, users can unset
    gcrypt-publish-participants.
  * Install nautilus hooks even when ~/.local/share/nautilus/ does not yet
    exist, since it is not automatically created for Gnome 3 users.
  * Windows: Move .vbs files out of git\bin, to avoid that being in the
    PATH, which caused some weird breakage. (Thanks, divB)
  * Windows: Fix locking issue that prevented the webapp starting
    (since 5.20140707).

### Please describe the problem.
Some internals of git annex does not check if the shell it is running is Posix-compatible, ie. bash.
I am using fish, and after setting up local pairing, and working, I switched back the login-shell to fish, and when syncing a file, I got this error, read from daemon.log:
fish: Unknown command 'GIT_ANNEX_SHELL_DIRECTORY=/home/s/annex'. Did you mean to run ~/.ssh/git-annex-shell with a modified environment? Try 'env GIT_ANNEX_SHELL_DIRECTORY=/home/s/annex ~/.ssh/git-annex-shell...'. See the help section on the set command by typing 'help set'.
Standard input: GIT_ANNEX_SHELL_DIRECTORY='/home/s/annex' ~/.ssh/git-annex-shell
^
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
### What steps will reproduce the problem?
Set up local pairing ( I believe having sh/bash as login terminal is necessary for this).
Switch back to fish as login-shell with chsh -s /usr/bin/fish
Add a file to either repository.
### What version of git-annex are you using? On what operating system?
