From af37a209ad76ce760becc0d2c2fac63c2022e730 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 15 Jun 2023 16:39:55 +0200 Subject: revision: small readability improvement for reading from stdin The code that reads lines from standard input manually compares whether the read line matches "--", which is a bit awkward to read. Furthermore, we're about to extend the code to also support reading pseudo-options via standard input, requiring more elaborate handling of lines with a leading dash. Refactor the code by hoisting out the check for "--" outside of the block that checks for a leading dash.
