It's fine with me if you push that to master and branch-2.5.  If it's 
really stable, you could even push something to branch-2.4.2, but that 
would require a manual update of m4/m4.m4 because branch-2.4.2 does not 
have an autoconf submodule.

Because this change is visible to the user, I'd also appreciate a brief 
NEWS entry for the earliest release.

Thanks, Eric.
