I found the description somewhere else and copied it into our header
file:
* From http://www.computerhope.com/cmd.htm:** 1. If all of the following conditions are met, then quote characters*
onthe command line are preserved:** - no /S switch* - exactly two quote characters* - no special characters
betweenthe two quote characters, where special* is one of: &<>()@^|* - there are one or more whitespace
charactersbetween 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,
stripthe leading character and remove the last* quote character on the command line, preserving any text after the
last* quote character.
