Motivation: Hook scripts for nautilus or other file managers
need to provide the user with feedback that a file is being downloaded.

Note that this is a nearly entirely free feature. The data was already
stored in the metadata log in an easily accessible way, and already was
parsed to a time when parsing the log. The generation of the metadata
fields may even be done lazily, although probably not entirely (the map
has to be evaulated to when queried).
For example "standard or (include=otherdir/*)" or even "not standard"
Note that the implementation avoids any potential for loops (if a
standard preferred content expression itself mentioned standard).

Old ssh did not check the hostname passed to -O stop, so I had used "any".
But now ssh does check it! I think this happened as part of the client-side
hostname canonicalization changes in 6.5p1, but have not verified that
introduced the problem.
The symptom was that it would try to dns lookup "any", which often caused a
bit of a delay at shutdown. And the old ssh connection kept running, so
it would do it over and over again.
Fixed by using localhost, which hopefully reliably resolves to some address
that ssh will accept.. Also nukeFile the socket after ssh has been asked to
shutdown, just in case.
From 1.7 gb to 900 mb on 300 thousand unique reported shas.
When shas are not unique, this streams much better than before, so won't
buffer the full list before putting them into the Set and throwing away
dups. And when fsck output includes ignorable lines, especially
dangling object lines, they won't be buffered in memory at all.
unused: In direct mode, files that are deleted from the work tree are no longer incorrectly detected as unused.
Direct mode `git annex info` slows down a bit due to more stringent
checking, but not by a lot.
Benchmarking this with 1000 small files being copied, the time reduced from
15.98s to 14.64s -- an 8% improvement in the non-data-transfer overhead of
git-annex copy.
git-annex-shell does not need a pty, so this speeds things up.
Also, it may avoid weird misconfigured systems that try to run screen or
tmux on every ssh login from doing so.
This is a new feature, it was not handled before, since it's a bit of an
edge case. However, it can be handled exactly the same as a file/dir
conflict, just leave the non-annexed item alone.
While implementing this, the core resolveMerge' function got a lot simpler
and clearer. Note especially that where before there was an asymetric call to
stagefromdirectmergedir, now graftin is called symmetrically in both cases.
And, in order to add that `graftin us`, the current branch needed to be
known (if there is no current branch, there cannot be a merge conflict).
This led to some cleanups of how autoMergeFrom behaved when there is no
current branch.

Added test cases for both ways this can happen, with a conflict involving a
file, or a directory.
Cleaned up resolveMerge to not touch the work tree in direct mode, which
turned out to be the only way to handle things.. And makes it much nicer.
Still need to run test suite on windows.
Using the extract(1) program to do the heavy lifting.
Decided to make git-annex run pre-commit-annex when committing. Since
git-annex pre-commit also runs it, it'll be run when git commit is run too,
via the pre-commit hook. This basically gives back the pre-commit hook
that git-annex took away. The implementation avoids repeatedly looking
for the hook script when the assistant is running and committing
repeatedly; only checks if the hook is available once.
To make the script simpler, made git-annex metadata -s field?=value
only set a field when it's not already got a value.

Note that negated globs are not supported. Would have complicated the code
to add them, without changing the data type serialization in a
non-backwards-compatable way.

Trying to start in such a repo will, obviously, fail.
Note that assistant --autostart will try to start in such a repo, and fail,
but does start successfully in the other autostart repos.
