Follow subfile patch for info.el
ht(a)inf.ed.ac.uk (Henry S. Thompson) writes:
It appears that some releases of makeinfo, in particular 5.1, which
ships with RHEL7, have a small incompatibility with the way we (and
Emacs) read subfiles. Although this problem doesn't arise in makeinfo
6, it would be good to fix it. Fortunately Emacs has a fix, described
here (along with analysis of the problem):
http://lists.gnu.org/archive/html/bug-texinfo/2013-04/msg00029.html
Could we have this done to our info.el, please? Note that it does
_not_ break forward compatibility to do this, i.e it works with old
(4.13), middle-aged (5.1) and young (6.0) versions of makeinfo.
Like so?

* info.el (Info-read-subfile): Follow change in Makeinfo 5.0 with
arithmetic of node positions.
I'll push on Tuesday if nobody objects.
