view configure @ 1724:81d8a7b20ce9 draft

sed depends on -r to be rightmost flag to simplify the REG_EXTENDED test. (If a flag is 1, you can multiply it by the value you want and get that value else zero without a branch or conditional assignment.) So move -E one to the left so FLAG_r is 1 again, and add a [+Er] suffix instead of testing FLAG_r | FLAG_E in the users.
