Hi,

I would find it less intrusive, if Emacs.app did not set INFOPATH upon
start up if it was not set before. This would enable users to make
changes to Info-default-directory-list in their initialization files. I
am attaching changes that imitate w32's behavior in this regard, albeit
adding the info directory in the bundle at the beginning of the list. It
might be prudent to change that if Emacs is built non self-contained. I
am a complete newcomer to changing Emacs "internals", so please forgive
me if this does not conform to emacs dev conventions.

If you decide against changing the behavior, I would find it helpful if
you included a hint in the documentation. This would spare users from
searching through Emacs.app/Contents/Info.plist,
~/.MacOSX/environment.plist or launchd.conf files, looking for the
definition of the INFOPATH.

Thanks!
