 completion script

- $TRASH_DIRECTORY is /c/dir style path, but git produces c:/dir style
  paths. Use $(pwd), which is short for $(pwd -W) that produces the
  latter, to assemble expected test data and paths read by git.

This comes up very often whenever somebody (including me) touches test
scripts.  We do have a write-up in t/README in "Dos and Don'ts" section,
but apparently that is not sufficient to avoid fix-ups.

Would it be possible to arrange so that $TRASH_DIRECTORY, $TEST_DIRECTORY
and $PWD are set to c:/dir style paths in Windows environment?  What would
we break if we did so?

The other direction of changing the Windows port of git to produce /c/dir
style paths would probably not work, as it would involve ripping out the
path mangling feature of bash in MSYS, which is done for some reason, I
presume.
