From 59fb87701ff68eb114e54ce6834e91c4ae8f60a7 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Wed, 27 Jun 2018 09:24:45 -0400 Subject: commit-graph: add '--reachable' option When writing commit-graph files, it can be convenient to ask for all reachable commits (starting at the ref set) in the resulting file. This is particularly helpful when writing to stdin is complicated, such as a future integration with 'git gc'.
