The reported problem persists even if I run with emacs -Q and for ALL
THREE settings of shell-file-name

1. The default value - cmdproxy.exe
2. (setq shell-file-name "sh")
3. (setq shell-file-name "bash")

*vc-dir* correctly reports modified files in my work area correctly for
 ALL the above settings.

side note: My "shell quoting" changes produces the expected behaviour in
case of 2 and 3. But fails for scenario 1.

ps: I see that my remark about sh.exe and bash.exe being same has
produced some confusion. What I meant was sh.exe and bash.exe are
DIFFERENT EXECUTABLE FILES (in physical sense) but with the SAME
CONTENT.
