Subject: Make "parse_object()" also fill in commit message buffer data.
X-Git-Tag: v0.99~454
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bd1e17e245153fdc75feaaf5e556b922d98ca699;p=git.git

Make "parse_object()" also fill in commit message buffer data.

And teach fsck to free it to save memory.
