RFR - 8143640: Showing incorrect result while passing specific argument in the Java launcher tool

[Rob McKenna]

Hi folks,

Looking for a review for this simple change:

http://cr.openjdk.java.net/~robm/8143640/webrev.01/

Basically the windows command parser was inserting extra slashes under certain circumstances.

cmdtoargs.c standalone test passes, as do the regression tests.
