>Description:
man(1) fails to display anything if $PAGER is set but blank. This can be confusing
as unset environment variables and ones with no value appear to be the same when
echoing.
>How-To-Repeat:
[mili:pgl]:~ $ export PAGER=
[mili:pgl]:~ $ man man
>Fix:
patch man's source to check for $PAGER with a non-zero value.
