Rephrase comments by Yann in order to hopefully
make the current situation clearer.

I hope the new text is OK for Yann, otherwise I
could revert and add as my own comment.

i think r1812339 should be an integral part of
the mod_journald backport and currently we do not
have any obstacle for the configure.in proposal.
The ap_expr fix was already backported, the
mod_remoteip fix does not apply to the 2.4 code
and the mod_journald fix IMHO should be voted and
applied together with the pending mod_journald
backport.
