• Fixed os.isfile() and os.isdir() when the specified name contains < or > or ", which are special wildcard characters for MS-DOS compatibility. This caused an error when typing "<, which then mistakenly thought a completion script named <.lua existed.
• Fixed rl.expandtilde() to omit a trailing backslash when expanding ~ by itself. This is to avoid running afoul of the \" parsing rules for argv[] for programs.
• Fixed potential crash when the clink command line takes more bytes as UTF8 than it does as UTF16.
