check on emptiness and support of catpages of a variable is necessary if it is
>Description:
if plain text man file are used, path to file stored in $catpage variables and $manpage remains empty. It breaks man_check_for_so from man(1) utility which tries to execute the "zcat -f" which will expect stdin. Check on emptiness and support for $catpage variable is necessary if this set.
>How-To-Repeat:
/usr/ports/archivers/rar ports, for example, used old style man:
% make -C /usr/ports/archivers/rar install
% rehash
% whereis rar
% man rar
it will hang to ctrl+d/ctrl+c
