  - fixed build problems on FreeBSD (and probably other Unices)

  - libiconv is not used for `conversion to ASCII' since never does the

    Right Thing, whatever it is

    instead of ISO-8859-2/CRLF

  * --list languages by default prints English names, instead of ISO-639a

    codes, use -e or -r to get the old listing

  * if LC_CTYPE is something like en_US, more locale categories are examined

    to detect the language

    as a fallback
