- add a knob WITH_CVS to use CVS repository as the distfile.
- install the localized manual pages to ${PREFIX}/man/ja, instead
of /usr/share/man/ja.
No objection from: kuriyama and metal
o Stop making a symlink ${PREFIX}/share/man/ja_JP.EUC, in order to avoid
that /usr/bin/man formats ja_JP.EUC manuals under it.
o pkg/PLIST becomes placeholder, because actual PLIST (work/PLIST) is
created dynamically based on doc/ja_JP.eucJP/man.
