This can't be it, because we're apparently cd-ing into cloneDir~"/dmd/src"
before calling "git ls-files". Excerpt of the log:

  Entering dir: clones\dmd\src
  Running: git ls-files
  Entering dir: C:\Users\VssAdministrator\AppData\Local\Temp\tmp.201CBA
  Copying the following files from 
  'C:\Users\VssAdministrator\AppData\Local\Temp\tmp.201CBA\clones/dmd/src' to
'C:\Users\VssAdministrator\AppData\Local\Temp\tmp.201CBA/dmd.master.windows/dmd2/src/dmd':
        ".azure-pipelines/lib.sh"
        ".azure-pipelines/windows-msbuild.bat"

Maybe the git bash sub shell does not notice "chdir"? Or is Phobos broken?
