Thanks a lot; I've been able to reproduce it. Here's a description of
what happens. Normally, info falls back to displaying the man page only
if it was not able to find the corresponding info document. When given
the --all option it works the same way, but the process is repeated
for each "dir" file in turn. Thus, the man page (provided that it exists)
is listed in the output only if the requested document was not
found in at least one of the encountered dir files.

In your first example, all dir files contain at least one reference to
automake, so info thinks that manpage is not needed at all.  In the
second case (emacs), the file /usr/share/info/dir contains no reference
to emacs, so info looks for a manpage itself.
