[Bug 1098373] [NEW] man terminfo (5) does not mention /etc/terminfo or /lib/terminfo

[Chris Good]

Public bug reported:

12.04.1 LTS man terminfo (5) says:

Fetching Compiled Descriptions
       If  the  environment variable TERMINFO is set, it is interpreted as the
       pathname of a directory containing the  compiled  description  you  are
       working on.  Only that directory is searched.

       If TERMINFO is not set, the ncurses version of the terminfo reader code
       will instead look in  the  directory  $HOME/.terminfo  for  a  compiled
       description.   If it fails to find one there, and the environment vari-
       able TERMINFO_DIRS is set, it will interpret the contents of that vari-
       able as a list of colon- separated directories to be searched (an empty
       entry is interpreted as a command to search  /usr/share/terminfo).   If
       no  description  is  found in any of the TERMINFO_DIRS directories, the
       fetch fails.

       If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will
       be the system terminfo directory, /usr/share/terminfo.

It doesn't mention /etc/terminfo or /lib/terminfo.
Thankfully I ran across command 'ncurses5-config --terminfo-dirs' which shows:
/etc/terminfo:/lib/terminfo:/usr/share/terminfo
or I would not have found /etc/terminfo/README which gives the 'good oil' :

This directory is for system-local terminfo descriptions. By default,
ncurses will search ${HOME}/.terminfo first, then /etc/terminfo (this
directory), then /lib/terminfo, and last not least /usr/share/terminfo.
