nope, that's not LuaSocket fault. someone else (author of affected
ftp-server) needs a test suite and, probably, some courses on carefull
specs reading. RFC 959 says this:
===
5.3.  COMMANDS
[some text ommited]
      field.  The command codes are four or fewer alphabetic characters.
      Upper and lower case alphabetic characters are to be treated
      identically.  Thus, any of the following may represent the
      retrieve command:
                  RETR    Retr    retr    ReTr    rETr
===
so LuaSocket is perfectly right here and ftp-server is perfectly wrong.
send a bug-report to server vendors, please.
