Unfortunately, I introduced a regression with this fix. On line 177
in man.vim, we're using "set nonu fdc=0" before we invoke the action in
the "open_cmd" variable. This means we're modifying the settings in
the initial window, before moving to the man page window.
The patch below will fix this regression, and it includes a test that
currently fails.

Scientists decoded the first message from an alien civilization:
SIMPLY SEND 6 TIMES 10 TO THE 50 ATOMS OF HYDROGEN TO THE STAR
SYSTEM AT THE TOP OF THE LIST, CROSS OFF THAT STAR SYSTEM, THEN PUT
YOUR STAR SYSTEM AT THE BOTTOM OF THE LIST AND SEND IT TO 100 OTHER
STAR SYSTEMS. WITHIN ONE TENTH GALACTIC ROTATION YOU WILL RECEIVE
ENOUGH HYDROGREN TO POWER YOUR CIVILIZATION UNTIL ENTROPY REACHES ITS
MAXIMUM! IT REALLY WORKS!
