Fix a regression caused in rev. 1.212, reported by kristaps@:

When using a pager and the first manual shown is gzip'ed,
the gunzip(1) process ended up as a child of the pager process
such that the man(1) process couldn't wait for it, preventing
proper display of the manual.

Solve this by making the pager a child of the man(1) process
(instead of the other way round), which requires being a bit
more careful about properly closing file descriptors after use
and waiting for the pager before exiting man(1).
