Hi, this is the second version of my patch series that replaces all uses of `test <expr> -o/a <expr`. Changes compared to v1: - I've expanded a bit on why we want to do these conversions in the first place in the first commit message. - Dropped a needless subshell and added missing quoting while at it. - Explained why we need to decompose the asserts in the second patch into two asserts. Thanks!
