Description of problem:
/usr/share/doc/lftp-4.0.7/NEWS states (correctly) that xfer:clobber
is off by default now, yet the man page still says "Default is on".
(And since the default has changed, "xfer:clobber" will be showing up
in error messages now, and people will look at the man page and wonder
why.)

Version-Release number of selected component (if applicable):
lftp-4.0.7-1.fc13.i686

How reproducible:
100%

Steps to Reproduce:
1. head -3 /usr/share/doc/lftp-4.0.7/NEWS	# right there on top
2. zgrep -A2 "xfer:clobber" /usr/share/man/man1/lftp.1.gz
  
Actual results:
From Step 1:
    Version 4.0.7 - 2010-04-29
    * make xfer:clobber off by default.
From Step 2:
    .BR xfer:clobber \ (boolean)
    if this setting is off, get commands will not overwrite existing
    files and generate an error instead. Default is on.

Expected results:
Man page should say "Default is off."

Additional info:
It is left as an exercise to show that xfer:clobber is indeed off now
by default.  Hint: Error message is:
    get: license.chm: file already exists and xfer:clobber is unset

Be aware that 'man lftp | grep "xfer:clobber"' will not show anything,
due to embedded overstrike characters.
