Subject: [PATCH] eselect-1.4.16

    Adds pager support for "$ eselect news read".

    Now the command "$ eselect news read" respects the environment variable PAGER. It is used only to show news items, not for e.g. messages like "no news is a good news". When stdin or stderr is not attached to the console, PAGER will not be used.

    The original code was written by "Teika kazura" <teika.gmx@com> (Swap the at-sign and the dot.) The commited version was contributed at Gentoo forum[1] by "steveL" [2]. The latter was chosen because of improvement in bash coding.

    The patch applies to 1.4.16.
