Or is that yet > another potential reason for the problem to happen only sometimes? Reasonably sure, yes. But I will try to pay more attention to this. I believe that I: 1. Discovered the problem with my setup, probably in E26. (See my other msg about why my setup led to the problem, which I just now figured out.) 2. Used emacs -Q in various releases, from 26 (and 27?) back through to 20. I was both (a) checking it is still a problem and (b) trying to find out whether it ever was OK and if so where the regression was introduced. I found that the problem was there starting with Emacs 24.5, that it worked in 24.4, and that before 24.4 the text was not linked. > AFAIR, we ended up giving up on understanding the exact reasons back > then as well, because you were unable to reliably reproduce the > problem, except in an old version of Emacs or an old version of Info > files. Exactly like now. That's possible. I don't recall. =20 > Which Info files Emacs finds is determined by the code which computes > Info-default-directory-list, and on code in info-initialize (and its > subroutine Info-default-dirs). In a nutshell, that makes Emacs > consider several alternative places until it finds one that "works". > So the answer to your question depends on the directories you have or > don't have on your system, out of those Emacs considers, something I > cannot know. It also depends on whether you have INFOPATH defined in > the environment, and if you do, what is its value. INFOPATH is nil. Each Emacs build is in a separate directory, and the dir contents are what is extracted from a Windows snapshot. I don't modify `Info-default-directory-list' or `info-initialize' when I use emacs -Q. (When I use my setup, I don't modify `info-initialize', but Cygwin does modify `Info-default-directory-list' to add "c:/cygwin/usr/info".) > > I don't see how different versions could show the same Info manual > > version when each is started with emacs -Q. >=20 > If you read the code in the functions I pointed to, you will see that > it doesn't only consider directories under the directory where you > unzipped the archive. It also looks in other places. Yes, but I don't do anything (when I use emacs -Q) that affects any of those places.
