// 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.

/**
* Creates a `lodash` object which wraps `value` to enable implicit method
* chain sequences. Methods that operate on and return arrays, collections,
* and functions can be chained together. Methods that retrieve a single value
* or may return a primitive value will automatically end the chain sequence
* and return the unwrapped value. Otherwise, the value must be unwrapped
* with `_#value`.
*
* Explicit chain sequences, which must be unwrapped with `_#value`, may be
* enabled using `_.chain`.
*
* The execution of chained methods is lazy, that is, it's deferred until
* `_#value` is implicitly or explicitly called.
*
* Lazy evaluation allows several methods to support shortcut fusion.
* Shortcut fusion is an optimization to merge iteratee calls; this avoids
* the creation of intermediate arrays and can greatly reduce the number of
* iteratee executions. Sections of a chain sequence qualify for shortcut
* fusion if the section is applied to an array and iteratees accept only
* one argument. The heuristic for whether a section qualifies for shortcut
* fusion is subject to change.
*
* Chaining is supported in custom builds as long as the `_#value` method is
* directly or indirectly included in the build.
*
* In addition to lodash methods, wrappers have `Array` and `String` methods.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
*
* The wrapper `String` methods are:
* `replace` and `split`
*
* The wrapper methods that support shortcut fusion are:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
* `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
* `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
