// \file
// \brief Contains two functions to compute expanded form of a given path.
//
// Given a path in the file system, compute an expanded form.
// An expanded path is one which does not
//  - involve any symbolic links
//  - involve any . or ..
//  - begin with a ~
//  - contain any trailing or repeated /
//
// The result of each query is cached so that a subsequent
// query on the same path will be much faster and will not
// involve any system calls.
