Subject: Make time-based commit filtering work with topological ordering.
X-Git-Tag: v0.99.8~98
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=27cfe2e2dcbfc4f6c6288ed4eafd077e232c2ab1;p=git.git

Make time-based commit filtering work with topological ordering.

The trick is to consider the time-based filtering a limiter, the same way
we do for release ranges.

That means that the time-based filtering runs _before_ the topological
sorting, which makes it meaningful again. It also simplifies the code
logic.

This makes "gitk" useful with time ranges.

[ Second version: --merge-order now unaffected by the re-org ]
