Translated mc manual pages may be converted to mc.hlp format

[Andrew V. Samoilov]

Hi!

I worked out a set of patches and now translated mc manual pages can be 
converted
to mc.hlp format.

Working example for Russian language can be downloaded as
http://www.linux.zp.ua/mc/mc.hlp.ru.tgz

There are doc/ru/mc.1.in, binary doc/ru/xnc.hlp and 3 patches for 
src/man2hlp.c
src/gindex.pl

ChangeLog:

* doc/ru: New directory for Russian translations.
* doc/ru/mc.1.in: New Russian translation of mc (1) manual page.
* doc/ru/xnc.xlp: Translated lib/xnc.hlp.

src/ChangeLog:
* man2hlp.c (main): Don't crash if man2hlp without parameters called.
(handle_command): New .\"NODE command added. Use in translated
mc manual to specify original .SH

* gindex.pl: Use [nodename] as user visible section name only if next 
line is
empty.  Elsewhere use this nonempty line.

* Makefile.am (mc.hlp.ru): Add rule to compile mc.hlp.ru.
