patch 9.1.2051: tests: fix Test_cd_completion fails in Appveyor
Problem: Test_cd_completion test fails in Appveyor. In Appveyor, a path
containing spaces was selected as the test target. But the
comparison failed because spaces were not taken into account
(after v9.1.2050)
Solution: Escape spaces in paths for comparison (Muraoka Taro)
