From 20d6421cae23d33fa153a9251360298ff7f1ce0a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 14 Feb 2017 01:04:17 -0500 Subject: grep: re-order rev-parsing loop We loop over the arguments, but every branch of the loop hits either a "continue" or a "break". Surely we can make this simpler. The final conditional is: if (arg is a rev) { ... handle rev ... continue; } break; We can rewrite this as: if (arg is not a rev) break; ... handle rev ... That makes the flow a little bit simpler, and will make things much easier to follow when we add more logic in future patches.
