The only problem with that is that PowerShell $HOME is not always
equivalent to Cygwin ~ .

For example, if the Windows user has a home drive and directory
specified in the profile, Cygwin ~ will point there rather than
PowerShell $HOME (which points at the user's profile directory).

I can make do with /bin/dash -c 'cygpath -aw ~' - from the Windows
side, but this makes me spawn two executables and seems like
unnecessary overhead.

Seems like there must be a better way...
