/**
*
* Specific implementation that quotes all the command line.
*
*
* Workaround for http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6468220
*
*
* From cmd.exe /? output:
*
*
*
* If /C or /K is specified, then the remainder of the command line after
* the switch is processed as a command line, where the following logic is
* used to process quote (") characters:
*
* 1. If all of the following conditions are met, then quote characters
* on the command line are preserved:
*
* - no /S switch
* - exactly two quote characters
* - no special characters between the two quote characters,
* where special is one of: &<>()@ˆ|
* - there are one or more whitespace characters between the
* the two quote characters
* - the string between the two quote characters is the name
* of an executable file.
*
* 2. Otherwise, old behavior is to see if the first character is
* a quote character and if so, strip the leading character and
* remove the last quote character on the command line, preserving
* any text after the last quote character.
*
*
* Always quoting the entire command line, regardless of these conditions appears to make Windows processes invoke
* successfully.
