Applied, thanks.
Comments:
* please, next time always use space around operators and after
commas, things like
week_number(xd&~TODAY_FLAG,month+which_cal+1,year,wflag);
are horrible.
* I don't understand this feature:
/* In some years (e.g. 2010 in ISO mode) it's possible to

For example:
$ LANG=de_DE.UTF8 ./cal --week=53 2009
Dezember 2009
Mo Di Mi Do Fr Sa So
49 1 2 3 4 5 6
50 7 8 9 10 11 12 13
51 14 15 16 17 18 19 20
52 21 22 23 24 25 26 27
53 28 29 30 31
it's correct, let's try the next year:
$ LANG=de_DE.UTF8 ./cal --week=53 2010
Januar 2010
Mo Di Mi Do Fr Sa So
53 1 2 3
1 4 5 6 7 8 9 10
2 11 12 13 14 15 16 17
3 18 19 20 21 22 23 24
4 25 26 27 28 29 30 31
oh... week 53 of the year 2010 in January 2010, but week 52 is December:
$ LANG=de_DE.UTF8 ./cal --week=52 2010
Dezember 2010
Mo Di Mi Do Fr Sa So
48 1 2 3 4 5
49 6 7 8 9 10 11 12
50 13 14 15 16 17 18 19
51 20 21 22 23 24 25 26
52 27 28 29 30 31
It seems pretty strange to interpret --week=53 2010 as last week
of the year 2009. I think it would be more intuitive to interpret
cal --week=53 2010
as invalid week number (or for another years expect this week after
week 52).
Note that I'm talking about command line --week=53 interpretations, the
week numbers in the output are correct of course.
