transferkeys had used special FDs for communication, but that would be
quite annoying to do in Windows.
Instead, use stdin and stdout. But, to avoid commands like rsync stomping
on them and messing up the communications channel, they're duplicated to a
different handle; stdin is replaced with a null handle, and stdout is
replaced with a copy of stderr. This should all work in windows too.
Stopping in progress transfers may work on windows.. if the types unify
anyway. ;) May need some more porting.
This works for both direct and indirect mode.
It may need some performance tuning.
Note that unlike git status, it only shows the status of the work tree, not
the status of the index. So only one status letter, not two .. and since
files that have been added and not yet committed do not differ between the
work tree and the index, they are not shown. Might want to add display of
the index vs the last commit eventually.

contribution as been going up lately! ;)
Note that it would be possible to extend the display to show all
repositories. But there can be a lot of repositories that are not set up as
remotes, and it would significantly clutter the display to show them all.
Since we're not showing all repositories, it's not worth trying to show
numcopies count either.
I decided to embrace these limitations and call the command remotes.
Works, more or less. --dead is not implemented, and so far a new branch
is made, but keys no longer present anywhere are not scrubbed.
git annex sync fails to push the synced/git-annex branch after a forget,
because it's not a fast-forward of the existing synced branch. Could be
fixed by making git-annex sync use assistant-style sync branches.
This is a simple approach for setting up a mirroring repository.
It will work with any type of remotes.
Mirror --from is more expensive than mirror --to in general.
OTOH, mirror --from will get the file from any remote that has it, not only
the named mirror remote. And if the named mirror remote is not the fastest
available remote with a file, that can speed things up.
It would be possible to make the assistant or watch command do a more
dynamic mirroring, that didn't need to scan every time.
I have seen some other programs do this, and think it's pretty cool. Means
you can test wherever it's deployed, as well as at build time.
My other reason for doing it is less happy. Cabal's handling of test suites
sucks, requiring duplicated info, and even when that's done, it fails to
preprocess hsc files here. Building it in avoids that and avoids having
to explicitly tell cabal to enable test suites, which would then make it
link the test executable every time, which is unnecessarily slow.
This also has the benefit that now "make fast test" does a max speed build
and tests it.
Now there's a Config type, that's extracted from the git config at startup.
Note that laziness means that individual config values are only looked up
and parsed on demand, and so we get implicit memoization for all of them.
So this is not only prettier and more type safe, it optimises several
places that didn't have explicit memoization before. As well as getting rid
of the ugly explicit memoization code.
Not yet done for annex.<remote>.* configuration settings.
Incomplete; I need to finish parsing and saving. This will also be used
for editing transfer control expresssions.
Removed the group display from the status output, I didn't really
like that format, and vicfg can be used to see as well as edit rempository
group membership.
Used by the assistant, rather than copy, this is faster because it avoids
using git ls-files, avoids checking the location log redundantly, and
runs in oneshot mode, avoiding making a commit to the git-annex branch
for every file transferred.
