changelog-merge plugin and edited ChangeLog entries

[Eli Zaretskii]

admin/notes/bzr has this passage regarding changelog-merge:

    Sigh.  This plugin has a drawback.  People often like to edit older
    ChangeLog entries, not at the head of the file.  Frequently they do
    this in the same commit as making new entries.  Using this plugin
    will merge ALL changed entries (including older ones) to the top of
    the destination file.

AFAIK, the number of people doing that is very small, so we could ask
them not to.

Regardless, would it be a good idea to ask for a modification of the
plugin, whereby it would error out in such cases, either by default or
under some option?
