- *
- * system.c
- *	   Win32 system() and popen() replacements
- *
- *
- *	Win32 needs double quotes at the beginning and end of system()
- *	strings.  If not, it gets confused with multiple quoted strings.
- *	It also requires double-quotes around the executable name and
- *	any files used for redirection.  Filter other args through
- *	appendShellString() to quote them.
- *
- *	Generated using Win32 "CMD /?":
- *
- *	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: &<>()@^|
- *	 - there are one or more whitespace characters between 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.
