a2229407e5 Prevent strange crashes in fmt with absurd goal lengths introduced by the
support for wide characters.

If the sizeof (wchar_t) times max_length would yield a value beyond
representation in a size_t, exit with a usage error up front, rather than
strange errors down the line from trying to malloc (well, realloc) with a size
of 0.

This is perhaps not the optimal behaviour - a clamp may be more appropriate as
we clamp the value of max_length now anyway, but this is at least better than
segfaulting or worse.  On systems which are friendly to malloc with a value of 0
the results could end up being strange corruption of the output.

ccb8bea4f0 The old fmt(1) always did what the new ``-l 8'' option does.
POLA: Changed the default to ``-l 8'' while still providing
a way to disable this feature with ``-l 0''.

3be5f1f5ce 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.
