bug#1188: Info reader and newlines in dir file

[dhruv@physics.utexas.edu]

I built and installed the MySQL Info manual.  The manual would show up
in the dir node when I invoked `info' from the command line but was
nowhere to be found when I invoked `info' within Emacs.  I tracked
this down to the fact that the MySQL entry in the Info dir node was
the last one and that there was no newline after it.  Inserted a
newline allowed Emacs to "see" the manual and load it up properly
inside Info running in Emacs.  This might be purposeful design, but it
feels like a bug to me: Emacs Info should behave like the command-line
info and not any different.
