Andrew Gallant 31d3e24130 args: prevent panicking in 'rg -h | rg' ... Previously, we relied on clap to handle printing either an error message, or --help/--version output, in addition to setting the exit status code. Unfortunately, for --help/--version output, clap was panicking if the write failed, which can happen in fairly common scenarios via a broken pipe error. e.g., `rg -h | head`. We fix this by using clap's "safe" API and doing the printing ourselves. We also set the exit code to `2` when an invalid command has been given. Fixes #1125 and partially addresses #1159		2019-01-26 14:39:40 -05:00
