If you want tilde-expansion to happen, you have to use a shell that does
tilde-expansion. bash and dash do, PowerShell does not.  It is not
cygpath's fault, but your choice of shell, that determines whether ~ is
expanded.  And, since the tilde-expansion of ~ is $HOME, and PowerShell
_does_ support $HOME, use $HOME instead of relying on tilde-expansion.
(The expansion of ~user is a much harder nut to crack - for that, you
really do depend on a shell doing proper tilde-expansion, as there are
no easy shortcuts)
