d77b331074 Suggections from bde@
1) Split too long source lines
2) Portable code should not assume that null pointer == all-bits-0,
so back out prev. calloc() change.

2a3fabc4d3 All cosmetic.
1) Rename RANDOM_MAX to RANDOM_MAX_PLUS1 to not confuse with random()'s max
2) Use calloc() instead of zeroing fields explicitly
3) "too many lines" -> "too many delimiters" for err()

2c38883d2a 1) Fix longstanding math bug with denominator > 1 (wrong probability).
Test case:
	random -f some_small_file 10000
(in most cases must be no output)
2) Prevent number of lines > RANDOM_MAX (overflow or nothing may be
choosed) with EFBIG err()
3) After line is found, terminate list loop for -U case too,
since nothing to do in the rest of the loop left.

67cc8dbb1a I was confused a bit by the wrong construction with RAND_MAX
used in randomize_fd.c.
Although the max value is the same currently, RAND_MAX is for rand(),
not for random().
So move RANDOM_MAX const to the common file now, make it UL and
use in randomize_fd.c too.
(in any case its old value was 1 less then must be, as noted in
the prev. commit)

5b6bf07632 1) Replace hardcoded RANDOM_MAX macro with wrong (1 less than must be)
value with ((double)RAND_MAX + 1)
2) For exit code increase valid denominator upper range from 255 to 256
since returned value is [0 .. denom - 1]

59c2bcbae9 Correct an error in the previous revision. RAND_MAX is the maximum value
for rand(3), not random(3).  random(3) is defined to return values between
0 and 2^31-1, so add a local RANDOM_MAX constant to this file that is
defined as 2^31-1 and use that in place of RAND_MAX.

b0a7bd8e88 Fix for 64-bit platforms. random() returns values between 0 and RAND_MAX,

3f4b504568 flexlint rears its head as well as some style(9) fixes[1]. Fixed a
few bugs for a few corner cases and correctly handle the case where
read(2) is read()'ing from a non-file descriptor and could get fewer
bytes back than the buffer, but it isn't EOF[2].  random(6) extensively
tested and believed to be bug free (save performance for large files).

077e7b24bc Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

01f228ffbe Wargh! Who went and changed all the getopt() comparisons from -1 to
EOF?  The getopt(3) manpage clearly states that the return value is *-1*,
not EOF!  Besides, getopt(3) isn't reading from a file. :)

Noticed-while:	merging to 2.2 (where this is correct).

of the x11 based games.  I'm not going to tag the originals with bsd_44_lite
and do this in two stages since it's just not worth it for this collection,
and I've got directory renames to deal with that way.  Bleah.
