Hi, all.

Enclosed is a gzipped copy of my calendar(1) mods. I didn't understand why
they were essentially ignored until I realised that I had changed the default
behaviour of calendar(1) without allowing for any way to get back to that
default behaviour.

So, here's another swing at it, this time with the default behaviour being
precisely what it is now, with my mods accessible via command-line options.

To wit, with my patch, there are two behaviours available, each of which may
be used seperately, or both together.

The '-r' flag turns on an extended warning checker, which looks for '+x' in
each line of the calendar files, where x is a (potentially multi-digit)
integer. This allows individual entries to have "look-ahead" dates exceeding
the default, which can still be set seperately. This output looks like this:

In 1 day: 10/14 Brian Joseph Andrew Leonard's Birthday

where the entry looks like this:

10/14 +14 Brian Joseph Andrew Leonard's Birthday

The next flag is '-y', which turns on a little year calculator, so that you
can have things like:

10/14 Brian Joseph Andrew Leonard's Birthday (1973: 25 years ago)

where the entry looks like this:

10/14 @1973 Brian Joseph Andrew Leonard's Birthday

Of course, both can be mixed, where you get:

In 1 day: 10/14 Brian Joseph Andrew Leonard's Birthday (1973: 25 years ago)

from the following entry:

10/14 +14@1973 Brian Joseph Andrew Leonard's Birthday

The point is that you might want to have a fourteen day warning for a friend's
birthday, but you might be annoyed that the only available way to get that
fourteen day warning also tells you that William the Conquerer won the Battle
of Hastings for those same fourteen days. Granularity is good.

I'd like to update the man page to describe this behaviour, but I'm not quite
sure how... Pointers will be welcome. (And, FWIW, I'd be slavishly grateful
if this made it into NetBSD. It's useful, small, clean, and it only shows up
if you ask for it.)

PS: I'm also send-pr'ing this. My previous calendar PR can be tossed.
