Comment (by kurtpayne):

 I have tested this on Windows + FileZilla Server (wasn't able to create
 symlinks here) and CentOS + vsftpd (with symlinks of varied and complex
 names).

 The `WP_Filesystem_FTPext::dirlist()` method uses
 [http://php.net/ftp_rawlist ftp_rawlist()] to get a file listing.  There
 is no standard format for this listing, so WP can't be assured that
 symlinks will be represented in `a -> b` format.  But the regex is
 targeted for that format and should skip over any new formats.  It should
 be a safe fix.
