/**
* \section tls
*
* tls -- Trivial recursive ls, for comparing two directories after
* running an rsync.
*
* The problem with using the system's own ls is that some features
* have little quirks that make directories look different when for
* our purposes they're the same -- for example, the BSD braindamage
* about setting the mode on symlinks based on your current umask.
*
* All the filenames must be given on the command line -- tls does not
* even read directories, let alone recurse. The typical usage is
* "find|sort|xargs tls".
*
* The format is not exactly the same as any particular Unix ls(1).
*
* A key requirement for this program is that the output be "very
* reproducible." So we mask away information that can accidentally
* change.
