Add a hook ``MANFILTER''. This optionally specifies a command to

pipe the man page source through before compressing or installing.
This can be used to do do (eg) sed substitution on man pages from
3rd party packages (in particular, ncurses and bind-4.9.4)

This should not affect anything already in the source tree.
