man-db Japanese support quick hack

[Fumitoshi UKAI <ukai@debian.or.jp>]

Package: man-db
Version: 2.3.10-69g
Severity: important (for Japanese user)

The current verison of man-db could not handle Japanese pages because
it always uses latin1 as nroff device.  I think man-db would not works
for other languages which is not using latin1 character sets, such 
as Korean/Chinese...

However, there are already jgroff/jless packages in debian. jgroff 
is the package replacing groff package and it provides `nippon' device to
handle Japanese roff pages correctly.

So, if we apply the following patch to man-db-2.3.10-69g and 
  install jgorff instead of groff
  install jless instead of less 
	(and set JLESSCHARSET environment variable as `japanese')
  install manpages-ja
then we can see Japanese manual pages!
I think it's better that manpages-ja depends on (or recommends?) 
jgroff and jless.

Note that the point of this patches are
  - detect manpages is Japanese or not by manpath of the man pages
  - if Japanese pages, add -Tnippon to nroff options

Of course, this is *very* quick hack, but it does not harm any users
and it works very well for Japanese users.  I don't know whether it
works for Korean/Chinese and so on.

BTW, we should think how to internationalize man-db.
