When commands are started from a subdirectory, they may have to compare the path to the subdirectory (called prefix and found out from $(pwd)) with the tracked paths. On macOS, $(pwd) and readdir() yield decomposed path, while the tracked paths are usually normalized to the precomposed form, causing mismatch. This has been fixed by taking the same approach used to normalize the command line arguments. * tb/precompose-prefix-too: MacOS: precompose_argv_prefix()
