5292d2aec0 Remove BUGS section that talked about missing multibyte character support.
We have support now that the regular expression routines do.

e27480d64d mdoc(7) police:
Revert to using the .Tn POSIX and .Tn ANSI instead of \*[Px] and \*[Ai]
strings; using these strings is unsafe in troff mode, as they include a
change in a font size.

c9885518de Create a small library function, check_utility_compat(3), to determine
whether a named utility should behave in FreeBSD 4.x-compatible mode
or in a standard mode (default standard).  The configuration is done
malloc(3)-style, with either an environment variable or a symlink.

Update expr(1) to use this new interface.

94a48596a3 EXPR_COMPAT should imply -e, since there is no way to specify it otherwise,
and -e reflects the historic behavior of FreeBSD's expr.

1393277e29 The response to my POSIX interpretation request says that `expr'
is required to be oblivious to overflow and to use the data type `long'.
(Division by zero is undefined in ISO C so it's still OK to check for it
here.)  Add a new `-e' flag to get the old, more useful behavior.

parsing for compatibility with old implementations.

f07e42470f Make expr POSIX-compliant, and fix some bugs. Specifically:
- expr must conform to the Utility Syntax Guidelines, so use
getopt() to eat the (non-existent) options.

- Use the Standard type intmax_t for arithmetic.

- If an argument cannot be *completely* converted to an integer, then
it is a string.

Additionally make some style cleanups near the modified lines.  This
utility is still not completely style-compliant.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.
