Subject: Don't add parents to the commit list if we have already
X-Git-Tag: v0.99~763
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=4056c09114e66ce3c2368551f0122e83628750d6;p=git.git

Don't add parents to the commit list if we have already
seen them.

Otherwise any merges will make the parent list explode.
