// the following quoting rules are very similar to the rules that by libuv applies.
//
// 1) wrap the string in quotes
//
// 2) double-up quotes - i.e. " => ""
//
// this is different from the libuv quoting rules. libuv replaces " with \", which unfortunately
// doesn't work well with a cmd.exe command line.
//
// note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
// for example, the command line:
// foo.exe "myarg:""my val"""
// is parsed by a .NET console app into an arg array:
// [ "myarg:\"my val\"" ]
// which is the same end result when applying libuv quoting rules. although the actual
// command line from libuv quoting rules would look like:
// foo.exe "myarg:\"my val\""
//
// 3) double-up slashes that precede a quote,
// e.g. hello \world => "hello \world"
// hello\"world => "hello\\""world"
// hello\\"world => "hello\\\\""world"
// hello world\ => "hello world\\"
//
// technically this is not required for a cmd.exe command line, or the batch argument parser.
// the reasons for including this as a .cmd quoting rule are:
//
// a) this is optimized for the scenario where the argument is passed from the .cmd file to an
// external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
//
// b) it's what we've been doing previously (by deferring to node default behavior) and we
// haven't heard any complaints about that aspect.
//
// note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
// escaped when used on the command line directly - even though within a .cmd file % can be escaped
// by using %%.
//
// the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
// the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
//
// one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
// often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
// variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
// to an external program.
//
// an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
// % can be escaped within a .cmd file.
