Modified files:
bin/expr expr.1 expr.y
Log:
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.
