Fixes basic case

This will fix the basic case listed in the comment (where command is eg. 'echo
a b c') but will not solve the reported problem.

There are 2 halfs to solve the reported problem and support for /F better:
1. You need to convert the 'delims' if supplied into a parameter passed into
WCMD_parameter, and all other callers should use the default (whitespace) -
Without this the reported problem would work but other simple for /F commands
will fail

2. tokens needs supporting - currently we assume the first thing on the line is
the only token, but we need to support eg. 1,3,4* which means 1st, 3rd and 4th
'parameter' gets mapped to variable name, variable name+1, variable name+2, and
+3 for the rest (eg for /F "tokens=1,3,4*" %a in ('echo a b c d e f g') do echo
%a %b %c rest:%d blank:%e)

Feel free to add a test when you get the test infrastructure in, and submit the
patch / clean it up
