[Cook] [PATCH] MANPATH for cook -help

[Lev S Bishop]

Cook goes to a lot of trouble to set MANPATH correctly before calling 
'man cook' when you type cook -help, but it incorrectly drops empty 
path-elements. In the words of my /etc/profile.d/xorg-x11-man-pages.sh:
# NOTE: MANPATH is special, it requires a leading : in order to
# search its default paths in addition to those specified in MANPATH.

Here is a patch to fix this:
