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.

717252ea98 Fix my own brokeness for the colon operator, when one of the arguments
was a valid integer.  The actual decision between integer and string
is now context-dependant on the operator being used.

2a353a9fb4 expr(1) didn't comply to Posix.2 and its own man page: any
comparisions have been made as string comparisions, even in cases
where both operands clearly qualified as integers.

The fix is to make the parser properly analyzing whether an operand is
a valid integer or not.

0fd510b71a You will find enclosed some changes to make gcc -Wall more happy in
/usr/src/bin. Note that some patches are still needed in that directory.

I (Joerg) finished most of Philippe's cleanup.  /bin/sh will still
need *allot* of work, however.

395b07d1df Explicitly include <sys/types.h> before including <regex.h>. This is
apparently required by POSIX.  It will be required in practice when
the bogus inclusion of <sys/types.h> is removed from <stdio.h>.

4a13ab7c12 Allow expressions like "expr 'ABC' : '^.*$' to work as is done in other
expr implementations.

4cf61aba29 Fix grammar to eliminate support for unary minus expressions -- they
weren't supported, they aren't standard, and they caused expr to dump
core.

55c497bf15 1003.2 requires that lexical comparisons be done in locale specific manner,
so we have to use strcoll() instead of strcmp().
1003.2 requires that a null string be returned if a string does not match
a \( \) subexpression.
Replaced fprintf/exit with calls to err and errx as appropriate.
