Ok, how about this patch? I do not have an access to the box with
AsciiDoc 8 handy right now, so I cannot test this myself, but there must
be somebody on the list who can give a quick test to this.
The procedure would be:
$ cd Documentation
$ rm -fr ./+old ./+new && mkdir ./+old ./+new
$ make git-{bundle,show-ref}.{html,1}
$ mv git-{bundle,show-ref}.{html,1} ./+old
$ git apply < this-patch
$ make git-{bundle,show-ref}.{html,1}
$ mv git-{bundle,show-ref}.{html,1} ./+new
$ git diff --no-index --color-words ./+old ./+new
Then eyeball the output, ignoring the timestamps and see if <sup>/<sub>
disappears and there is no other change. Other documentation pages should
also be verified, but these two are I know of with the issue.
