        //
        // 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.

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
