bugfix: lib/sh/util.sh: PATH_rm(): also need to remove adjacent occurrences of the same path (or occurrences which become adjacent when other paths are removed), which :...: matching wasn't doing because the trailing : is consumed, preventing it from being matched at the beginning of the next path. since unlike filesystem paths with /, it is not necessary for a match to span multiple :-separated sections, we can just use new split() to split apart the PATH into an array of paths, filter each path, and join() them back together.
