Hello, coreutils maintainers.
Command expr in version 8.25 of coreutils seems for me to treat
0 in character class in paren incorrectly.
$ for i in {a..z}; do expr $i : '\([a-z]\)$' >/dev/null || echo failed at $i;
done
$ for i in {1..9}; do expr $i : '\([1-9]\)$' >/dev/null || echo failed at $i;
done
$ for i in {0..9}; do expr $i : '[0-9]$' >/dev/null || echo failed at $i;
done
$ for i in {0..9}; do expr $i : '\([0-9]\)$' >/dev/null || echo failed at $i;
done
failed at 0
$ for i in / 0 1 ; do expr $i : '\([/-1]\)$' >/dev/null || echo failed at $i;
done
failed at 0
$ for i in . / 0 ; do expr $i : '\([.-0]\)$' >/dev/null || echo failed at $i;
done
failed at 0
$ for i in {00..99}; do expr $i : '\([0-9][0-9]\)$' >/dev/null || echo failed
at $i; done
failed at 00
$ for i in {000..999}; do expr $i : '\([0-9][0-9][0-9]\)$' >/dev/null || echo
failed at $i; done
failed at 000
