I don't have a cygwin at hand, but yes. This is the problem, cygwin uses
something like /cygdrive/c/foo for c:\foo. Why not give up and add
commandline option(s) to darcs to invoke cygwin-openssh vs putty
behaviour? I think darcs also doesn't allow putty sessions to be
used, and if we had option, we could invent syntax for that.
How about --enable-workaround=foo and --disable-workaround=foo?
FWIW, attached is a little Haskell program I use on Windows to impedence-match
between cygwin OpenSSH (actually scp) and darcs. It also handles MSYS,
instructions are in the file.

-- Wrapper for using cygwin/msys scp with darcs on Windows.
-- Use as follows:
-- - compile with 'ghc --make scpwrap.hs -o scpwrap'
-- - set the environment variable DARCS_SCP=/path/to/scpwrap.exe
-- - if scp is not in your path, set REAL_DARCS_SCP to point to it
-- - the script tries to detect whether you're using msys or cygwin:
-- if scp is found along a path that contains "msys", then it assumes
-- msys, otherwise cygwin. If this is wrong, then you'll have to
-- modify the script.
