TCSH is an extended C-shell with many useful features like
filename completion, history editing, etc.
This also supports
1. Multibyte command-line editing
2. Multibyte NLS catalogs
3. colorlized ls-F command
See also ${PREFIX}/share/doc/tcsh.
Use ${ECHO_CMD} instead of ${ECHO} where you mean the echo command; the ECHO
macro is set to "echo" by default, but it is set to "true" if make(1) is
invoked with the -s option while ECHO_CMD is always set to the echo command.
Change PKGDIR from pkg/ to . Also fix places where ${PKGDIR} is spelled out
(many of which are ${PKGDIR}/MESSAGE -> ${PKGMESSAGE} type fixes that
shouldn't have been necessary) and the string "/pkg/" appear.
Disable these ports for versions with /bin/tcsh. japanese/tcsh is not needed
since NLS support is already in /bin/tcsh, and the message catalogs are
currently useless since we can't switch them easily.
