asciidoc: ifdef::<>[] macros are not supported

[jnavila]

The following snippet of text make po4a choke:

ifdef::stalenotes[]

with the following error:

parse...po4a::asciidoc: Impossible d'analyser la liste d'attributs : []

[jnavila]

The same for include::date-format.txt[] that appears in the man page of git-commit.txt.

https://github.com/git/git/blob/master/Documentation/git-commit.txt#L344

This is really a show-stopper for po4a and asciidoc.

OK, trying to fix the issue, it appears that it is already fixed by 86f79e5 but this version hasn't reached debian/testing yet. Compiling and using the most up to date version solves this issue.

Whooops, I completely forgot that the latest release did not contain all recent changes. I will try to find some time to release and upload a new version in the next times... Sorry.
