Info-default-directory-list

[Perry Smith]

Hi,

Info-default-directory-list comes up on one of the systems I use with a list 
that is the configure-info-directory plus /usr/local/share

But on this system, I do not have permission to read or search 
/usr/local/share.  It exists but I can’t read or search it.  I don’t own this 
system.

This causes a few issues.  The info list is truncated and helm does not compile 
(or even load).

For now, I’ve customized it with this:
 '(Info-default-directory-list
   (delq nil (mapcar (lambda (x) (and (file-executable-p x) x)) 
Info-default-directory-list)))

Most of the processing uses file-exists-p and I’m wondering if that is really 
what is most desirable here.  It seems that in general the existence of a 
directory is uninteresting unless the directory is at least readable and 
probably users want to search it too.  In the specific case of Info’s 
directories, the user clearly needs to read it and probably search it.

Do others agree?  Should this be a bug report?

Thank you,
Perry
