Re: ChangeLog entry timestamp

[Richard Stallman]

    Actually, the date should be the date it was committed, so it should
    be sorted.  Not sure about what should happen in case of merges, tho.

A merge into the trunk should be treated like any other installation
into the trunk.  The change log entries should look the same as they
would if the changes had been installed some other way.

This is because, that if you are merging into the trunk, you should
combine and simplify the change log entries.
