Not just unnecessary, but positively harmful.  Several shells will fail 
to parse this correctly, *including* the MSYS version of bash.  See:

`pwd -W' is an MSYS extension, (it displays the native MS-Windows path, 
rather than the POSIX style favoured by MSYS).  Some shells will simply 
ignore it, (e.g. `sh' on SunOS-5); others treat it as an error, (e.g. 
`bash' other than in MSYS, Cygwin's `ash').
