Special man command

If you use less as pager for man you can try

LESS="+/^\s+-b" man wget

where

1. + symbol to execute next operation after less has opened
2. / command to start search
3. ^\s+-b regexp to match -b from start of line

So if you like you can arrange the apropriate function for shell

function rman {
#USAGE: rman programm.name option.to.search (with "-" symbol)
LESS="+/^\s+$2" man "$1"
}

and add it into ~/.bashrc for example.
