* Add first draft of new osproc.readLines * Add test for new osproc.readLines * Rename test to start w/t to run; Also add newline to output * Suppress hint messages. * Output should match this time. * Shoulda picked a program with simpler syntax than ..lol * Address https://github.com/nim-lang/Nim/pull/15429#issuecomment-701890898 and https://github.com/nim-lang/Nim/pull/15429#issuecomment-701985976 by factoring `readLines` into `iterator lines` and a wrapper `proc`. * Address https://github.com/nim-lang/Nim/pull/15429#issuecomment-702127289 and also add a `ReadIOEffect` tag to the iterator (called by the wrapper.. so it should need no separate tag, if I understand correctly).
