Thanks for looking into the patch.
No. Thank _you_ for contributing ;-)
Vim buffers are not reorderable and windows are always numbered from
top-left to bottom-right. However, I can see someone who is familiar with
the old behavior issue a "CTRL-W_K" command to move the merged window from
the bottom to the top, making the merged window the first window and
consistent with buffer indexes. If they use this command after the patch,
the indexes would no longer be consistent. The command would most likely be
issued manually and not through a vim startup script.
So it should suffice to mention it in the release notes as one
bullet item that describes one positive change, among all other
updates described in a simlar way. And there is no special
"warnings for existing users" necessary, I would say.
Thanks.
