Not tested yet.
The EvilLinker workaround is removed. That got fixed in ghc 8.0.1,
(per https://ghc.haskell.org/trac/ghc/ticket/8596)
which will finally be used by the windows autobuilder now.
I have not deleted the EvilLinker yet (or closed its bugs).

This is pretty complicated, but I have both "git-annex" and "git annex"
working both in the git bash shell even with git not added to path.
And, when git's added to path, both work from MS-DOS prompt window too.
I think that the webapp startup does still need git in path, so
instructions will keep saying to do that. But, users often disregard them,
and hopefully this will reduce support traffic.
Also, switched the wget from the cygwin one to the msys2 one, avoiding the
complication of needing to bundle any cygwin dlls.
Using msysgit with git-annex is no longer supported.
At the same time, I'm updating the rsync.exe in my downloads repository
with the one from msys2.
Note that rsync is currently still being ldded and installed in Git/cmd/
like the other cygwin programs. The ldd fails and this failure is ignored.
It would be better to special case it to go in Git/usr/bin/, so that the
user can't run rsync in a dos prompt window, which doesn't work, as it needs
additional libs. However, as far as git-annex running rsync running ssh,
it works ok in this location.
Removed the ssh.cmd and ssh-keygen.cmd; these are not needed with git for
windows. Keeping them would let ssh be run manually from a dos prompt
window, but that's not really a goal.
