{- On Windows, if HOME is not set, probe it and set it, re-execing
- git-annex with the new environment.
-
- This is a workaround for some Cygwin commands needing HOME to be set,
- and for there being no known way to set environment variables on
- Windows, except by passing an environment in each call to a program.
- While ugly, this workaround is easier than trying to ensure HOME is set
- in all calls to the affected programs.
