Subject: rev-list --max-age, --max-count: support --boundary
X-Git-Tag: v1.5.1-rc1~136^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c4025103faf02a1b457b945cf5e4e12c97fa72d7;p=git.git

rev-list --max-age, --max-count: support --boundary

Now, when saying --max-age=<timestamp>, or --max-count=<n>, together
with --boundary, rev-list prints the boundary commits, i.e. the
commits which are _just_ not shown without --boundary, i.e. their
children are, but they aren't.
