Sergey Biryukov b2ffea836b Docs: Fix typos in wp-admin/includes/class-pclzip.php. 
With the upstream library not updated in 10 years since the last time it was merged, it should be safe to treat it as "adopted" rather than external, and make these fixes.

Props passoniate, ottok.
Fixes #49163. See #38464.
Built from https://develop.svn.wordpress.org/trunk@47123

// Presentation :
// PclZip is a PHP library that manage ZIP archives.
// So far tests show that archives generated by PclZip are readable by
// WinZip application and other tools.
//
// Description :
// See readme.txt and http://www.phpconcept.net
//
// Warning :
// This library and the associated files are non commercial, non professional
// work.
// It should not have unexpected results. However if any damage is caused by
// this software the author can not be responsible.
// The use of this software is at the risk of the user.

// ----- File list separator
// In version 1.x of PclZip, the separator for file list is a space
// (which is not a very smart choice, specifically for windows paths !).
// A better separator should be a comma (,). This constant gives you the
// ability to change that.
// However notice that changing this value, may have impact on existing
// scripts, using space separated filenames.
// Recommended values for compatibility with older versions :
//define( 'PCLZIP_SEPARATOR', ' ' );
// Recommended values for smart separation of filenames.

// Pclzip sense the size of the file to add/extract and decide to
// use or not temporary file. The algorithm is looking for
// memory_limit of PHP and apply a ratio.
// threshold = memory_limit * ratio.
// Recommended values are under 0.5. Default 0.47.

// a string containing one filename or one directory name, or
// a string containing a list of filenames and/or directory
// names separated by spaces.
// $p_add_dir : A path to add before the real path of the archived file,
// in order to have it memorized in the archive.
// $p_remove_dir : A path to remove from the real path of the file to archive,
// in order to have a shorter path memorized in the archive.
// When $p_add_dir and $p_remove_dir are set, $p_remove_dir
// is removed first, before $p_add_dir is added.

// folder : true | false
// index : index of the file in the archive
// status : status of the action (depending of the action) :
// Values are :
// ok : OK !
// filtered : the file / dir is not extracted (filtered by user)
// already_a_directory : the file can not be extracted because a
// directory with the same name already exists
// write_protected : the file can not be extracted because a file
// with the same name already exists and is

// newer_exist : the file was not extracted because a newer file exists
